Original Description of AiioEs grossbecki: 



The New Jersey specimens identified as " Culex squamiger Coq." by Mr. Coquillett 

 and published by Prof. Smith we fully believe to be a distinct species. Mr. Quayle 

 records (Can. ent., xxxviii, 27, 1906) the true squamiger (Coquillett, Proc. U. S. Nat. 

 Mus., XXV, 85, 1902) as a salt marsh species from the Calif ornian coast, to which it 

 is no doubt confined. The New York records of " Grahliamia curriei Coq." seem to 

 refer to the present species. Unfortunately we have not been able to secure Cali- 

 fornian larvae for comparison, although Mr. Quayle kindly endeavored to supply us. 

 It is quite possible that the Culex onondagensis Felt (Bull. 79, N. Y. Sta. Mus., 304, 

 1904) may prove to be this species, in which case our new name may be placed in the 

 synonymy. 



The following- is an abstract of the table :

8. Pecten of the air tube with evenly spaced teeth 13 



13. Comb scales more numerous to many in a patch 21 



21. Anal segment not ringed by the plate 31 



31. Tube three times as long as wide or less 32 



32. Anal plate covering more than half the segment; anal gills 



moderate 33 



33. Comb scales tapered, a single median spine stouter or longer,

34. Lower head tuft single or double (rarely three) 37 



37. Lower head hair double (or three) 38 



38. Comb scales with the lateral spines as long as the apical one

 Original Description of Culex sylvicola: 



5. Length, 6-7 mm. Head brown, occiput clothed with whitish scales and a patch 

 of brown ones on each side of the median line contiguous to the eyes; antennae 

 brown, the basal joint and two following ones ochreous; proboscis and palpi blackish- 

 brown, slightly sprinkled with white scales, the latter with the third joint rather 

 long, the apical one minute, rounded, white scaled. The dorsum of the mesonotum is 

 covered with cinereous scales, and a broad, median, dark brown vitta extends 

 forward from the posterior margin, which becomes narrow anteriorly and golden- 

 brown in colour; two other dark brown marks extend from the posterior margin not 

 quite to the middle of the mesonotum, separated from the median vitta by a narrow 

 line; scutellum cinereous, with brown bristles on the posterior margin; metanotum 

 evenly brown; pleura brown, with dense, fluffy patches of whitish scales; halteres 

 yellowish, tipped with brown and white. Abdomen blackish-brown above, with a 

 few whitish scales intermixed; segments one to five have each a broad yellowish 

 white band at the base, segments six and seven with an additional narrow apical 

 band; beneath it is dirty white, with a few brown scales; genitalia brown. Legs 

 dark brown, femora and tibiae profusely sprinkled with whitish scales, the former 

 yellowish on the posterior portion and at the knees; claws uniserrated; wings 

 hyaline, the veins covered with broad brown and white scales, and also some narrow 

 brown ones on the apical third, petiole of first submarginal cell almost two-thirds 

 the length of this cell. 



(^. Palpi dark brown, the first joint whitish at the base, and with a yellow band 

 in the centre; bases of the two terminal joints also whitish In some specimens; fan- 

 like tufts brown, with yellow reflections. Abdomen with the bands restricted in the 

 centre; claws uniserrated; petiole of first submarginal cell almost as long as this 

 cell. 



Genitalia: Clasp elongate, inner margin rounded apically; subapical lobe present, 

 prominent, projecting laterally, setose; basal lobe well developed, setose, a long spine 

 arising near it, which is curved at the tip; clasp filament long, curved, two small 

 setae near the apex, with long apical spine. Harpe jointed, basal segment curved, 

 swollen basally; apical segment long, dilated centrally, tip curved. Harpago hood- 

 shaped, tip bent laterally. Appendage of eighth segment with long setae.
