Classification of the Culicitk-e. 249 



fliit ovevlappino- squames. The scales of the scutum are 

 often broadly elliptical. As a rule some of the wing-scales 

 are broad triangular plates. The second marginal cell of tiie 

 Aving is very small. Palpi very short in both sexes. Small 

 or minute insects, commonly with beautiful blue markings. 



e. Genera of the Psorophora type. — The predominant 

 scales of head, scutum, and scutellum are elliptical squames, 

 which may be either flat or curved and are often rather 

 distant. In those forms where both sexes are known the 

 palpi are short in the female and long in the male. 



f. Genera of the Mucidus type. — The head is shaggy with 

 upstanding scales of several kinds, among which either coarse 

 falcate scales or broad cuneiform or fiabelliform scales are 

 conspicuous. The wings are speckled or mottled, or they 

 may be spotted — in field, costa, and fringe — like those of a 

 JVyssor/iynchus. The legs also are, as a rule, much banded 

 or brindled. The wing-scales are either broadly foliaceous 

 or broadly subtriangular. The palpi may be quite short in 

 both sexes, or nearly as long as the proboscis in both sexes, 

 or long in the male and short in the female. The mos- 

 quitoes of this group seem to link the Culicales with the 

 Epiahirgi. The following forms belong to this group : — 

 Mucidus, 'Y.h.QohdXa (^=-LepidoplatySf Coquillett) ; Mansonia, 

 Blanchard {^—Pneumaculex, Dyar); MansonioideSj'\^\\eohsi\A; 

 Etorilepidoinyia, Theobald ; Orthopodomyia, Theobald ; NeiO' 

 steadina, Theobald ; Aedimyia, Theobald ; Finlaya, Theobald. 



g. Annectant forms between Culex and Stegomyia — in 

 which the squames of the cheeks, which in Culex are not 

 visible in a dorsal view, extend more or less on to the crown 

 of the lieadj and do not lie flat as in Stegomyia, though they 

 overlap, and in which the scales of the scutellum are either 

 exclusively falculate as in Culex or are combined with over- 

 lapping squames. Acartomyia, Theobald, may be taken as a 

 standard, and all the seven '' genera" — each of which rests 



^on a single species — that can be collected into tins group 

 might be united. 



Section 4. Metanototricha. 



The species included in this small section resemble 

 Culicales, particularly those of the Stegomyia and Aedes 

 groups, but are distinguished by having a few inconspicuous 

 bristles or scales (or both bristles and scales) on the meta- 

 notum.
