118 THE MOSQUITOES OF NEW JERSEY 



at Lake Hopatcong, July 30 at Chester, September 10 and 16 at 



Chester. 



In its general habits it does not differ from the other woodland mos- 

 quitoes, and while it bites, it is not vicious and causes no unusual pain 

 or swelling. Of its method of passing the winter we know nothing 

 definite ; but it is likely that it is in the egg stage. 



DESCRIPTION OF THE LARVA 



Full grown measures 5.5-6mm. (.22-.24< inch) excluding anal si- 

 phon ; pale gray to dark gray in color. Head one and one-half times as 

 broad as long, yellowish, with large brown blotch on the anterior part 

 of vertex, similar to Aedes vexans. Four hair tufts in center of vertex, 

 of four or five hairs each, and larger one at base of each antenna. 

 Antennae rather short, slightly curved, pale yellow, faintly infuscated 

 apically ; thickest short distance from base and with surface sparsely 

 set with stout spines and numerous small ones arranged in longitudinal 

 rows. Tuft, situated well below middle, consists of eight or ten hairs 

 which do not reach the apex ; apex with one long spine, several smaller 

 ones and a small joint. Rotary mouth brushes dense, with hairs of cen- 

 tral part pectinated. Mentum triangular with fifteen to seventeen small 

 teeth on each side of apex. Mandible and maxillary palpus normal, 

 latter with moderate apical tuft and stout basal joint. 



Thorax very much broader than long, with angulated sides, each 

 angle set with acute infuscated tubercles from which issue moderate 

 sized hair tufts. Two very small tufts near anterior margin. Abdominal 

 segments subequal, each bearing lateral hair tufts of from two to five 

 hairs each, larger number on anterior segments. Lateral patches of 

 scales on eighth segment large, having from twenty-five to thirty in 

 each patch. Individual scale elongated, with rather small apical spine 

 and smaller ones fringing sides. Anal siphon two and one-half times, or 

 slightly over, as long as broad, yellowish brown, thickest near base and 

 tapering a little apically. From sixteen to twenty spines in each row, 

 single spine with one or two teeth near base. Ninth segment almost 

 square, nearly ringed by chitinized saddle ; with double dorsal tuft and 

 ventral brush normal and moderate in size, latter with several small 

 tufts below barred area. Tracheal gills slender, about two and one-half 

 times length of ninth segment, taper to a point. 



HABITS OF THE EARLY STAGES 

 A mixture of full grown larvae and pupae was taken from a wood- 

 land pool in the Great Piece meadows May 10, 1904. All the larve were
