 Affinities (Diptera, Culicidae). — Insecutor Inscitiae Menstruns,

This paper deals with the classification of the genus Aedes based 

 on the structure of the male genitalia. This basis of classification 

 supersedes that of adult coloration, since it shows the relationship 

 existing between New and Old World species.

The errors in the classification of the genus Cidex that appeared 

 in the author's monograph are now corrected by the adoption of a 

 new basis of classification, which has resulted in a reduction of the 

 number of species to be recognised.

 Culicidae). — Insecutor Inscitiae Menstruus, Washington, D.C, vi, 

 nos. 4-6, April-June 1918, pp. 112-115. 



This paper deals with the genus Taeniorhynchus [Mansonia), to 

 which a key is given. It is divided into two subgenera, Mansonia, 

 Blanchard, in which the eggs are attached to the under-side of floating 

 leaves, and Coquillettidia, Dyar, in which they are deposited in floating 

 boat-shaped masses. The species included in the former are Taenior- 

 hynchus (Mansonia) titillans, Wlk., T. {M.) pseud otitillans, Theo., 

 T. (M.) humeralis, D. & K., T. (M.) amazonensis, Theo. Belonging 

 to the latter are T. jperturhans, Wlk., T. nigricans, Coq., T. coticula, 

 D. & K., T. fasciolatus, Lynch A., T. arribalzagae, Theo., T. juxtaman- 

 sonia, Peryassu, T. albicosta, Peryassii, and T. hypodndyna, sp. n., 

 from Brazil.

 14 figs. [Received 13th May 1918.] 



This bulletin deals with the usual external parasites of poultry, 

 mention being made of some that have not yet been recorded in Ohio. 



These include : — Menopon pallidum, Olfers [trigonocephalmn) (small 

 body louse) and M. hiseriatum, Piaget (large body louse), methods 

 for controlling which have already been noticed [see this Review, 

 Ser. B, iii, p. 158] ; Lipeurus heterograjjhus, N. (head louse), abundant 

 on young chickens, though not so frequently met with as the two 

 preceding species, cannot be controlled by the same remedy, but is 

 best dealt with by rubbing mercurial ointment into the bases of the 

 feathers ; L. caponis, L. (variabilis) (variable hen louse) ; Goniocotes 

 gigas, Tasch. (abdominalis) (large chicken louse) ; G. gallinae, 

 Retz. (hologaster) (lesser chicken louse) ; Goniodes dissimilis, N. ; 

 Dermanyssus gallinae, De G. (red mite, poultry mite) and D. hirundinis, 

 Hermann (bird mite), the life-history and control measures for which 

 have already been noticed [see this Review, Ser. B, v, p. 173] ; Trom- 

 bidimn sp. (harvest mites, chiggers), the larvae of which may attack
