 Soc. Entoni. France, Paris, 1920, no. 16, 27th October 1920, 

 pp. 269-272. 



The genital armature of Culicids is discussed, with reference to the 

 recent paper of Edwards [R.A.E., B, viii, 156] and his criticism of 

 the author's previous observations.

The mosquitos dealt with in this paper, as being either new or little 

 known to the French fauna, are Culex laticinctus, Edw., conimon 

 in the Mediterranean region ; jAedes (Stegomyia) vittatus. Big. ; A. 

 {Finlaya) geniculatiis, 01., which is abundant and widely distributed, 

 and was previously recorded from Corsica as A . jugorum ; Ochlerotatus 

 maculatns, Meig., the larvae of which were found in a small, isolated 

 marsh at Meudon, in May ; 0. lesnei, Seguy, from Seine-et-Marne, etc. ; 

 0. niariae, Serg., from Toulon ; 0. curriei, Coq. ; 0. caspius, Pall. ; 

 0. punctor, Kirby ; 0. sticticiis, Meig. ; and Orthopodomyia pulchripaipis, 

 Rond., a rare species. 



It is remarked that this latter species, hitherto placed in Grabhamia 

 or Ochlerotatus, should certainly belong to Orthopodomyia. The larvae 

 of this genus live in water-holes in trees, in company w'lih. A. geniculatus, 

 01., and Anopheles {Coelodiazesis) plumbeus, Hal.

 Attention is drawn to a paper by Bacot [R.A.E., B, viii, 3] in which 

 the world-wide distribution of Pulex irritans is emphasised. Similar 

 statements have been made elsewhere, and as the author's theory of 

 the transmission of rheumatic fever by fleas is based on their 

 geographical distribution [R.A.E., B, viii, 75], the occurrence of 

 P. irritans in the tropics would destroy it. A request is made for the 

 publication of the evidence on which the statements that P. irritans is 

 ubiquitous are based.

A solution of two grains of powdered para-dichlorobenzene or 

 camphor, in lump or powder, to one litre of water, renewed every 

 10 days, has pro^^ed a successful measure against the yellow fever 

 mosquito [Stegomyia fasciata]. It is especially convenient for use in 

 such breeding places as flower vases and other water containers in 

 which the use of oil is impracticable.

Progress towards the completion of the life-histories of Tahamis 

 phaenops and T. pnnctifer is described. The introduction of egg- 

 parasites for the control of T. phaenops was attempted, but the results 

 cannot yet be ascertained. 



A difficult feature of the studies was the egg-laying habits of T. 

 pJuicnops, the most troublesome of the ffies recorded. A considerable
