The lice which infest man belong to the order Anoplura Leach 1817, containing two sub-orders, (i) Siphunculata Meinert 1891 and (ii) Mallophaga Nitzsch 1818. The family Pediculidae Leach is included in the Siphunculata 1 . Owing to the confusion which still persists in the literature regarding the nomenclature and systematic position of the two sub-orders of Anoplura, it appears expedient to review the evidence upon which the statement contained in the preceding paragraph is based.

A variety of substances has been tested by laboratory methods as insecticides against the bed‐bug and the body‐louse. The oil‐soluble samples were tested by the Potter tower method which gave the most accurate results. Certain liquids were tested by a simple dipping method, and solids insoluble in mineral oils were tested as aqueous solutions by the dipping method or as dusts. Various organic thiocyanates were found to show similar relative toxicity to the louse and bug, but the pyrethrins were ...

The author has examined 1437 crops of hair, removed from adult or adolescent males on admission to jail, at Cannanore, South India. There is a high positive correlation between weight of hair and rate of infestation with head-lice, men with less than 10 g. of hair being 14·6% infested, those with 10–19·9 g. 39·9%, and those with over 20 g. 56–59%. There appears to be a negative correlation with age, but this seems to be due to the older men having less hair: if one standardizes hair weight there ...

The precise biology of the body louse under experimental conditions is a subject not sufficiently explored. At present we need quantitative information about the possible rate of increase of the insect: we must also know about the normal biology in studying insecticides. The present moment is therefore an appropriate one for publishing certain experiments which have occupied a part of my time for the last 4 years.

1. Measurements were made of the head length, head width, total body length, antenna length, length and breadth of 3rd antennal segment of head and body lice from natural infestations. In all measurements (except the last) the means were significantly different for. the two forms, but in all cases there was considerable overlap. 2. Head lice reared continuously on the body for forty-three generations (over 2 years) did not change systematically in size. Body lice reared under similar conditions were ...
