BY D. W. COQUILLETT, WASHINGTON, D. C. 



Culcx cantator. new species. — Female. Near sylvestris, but the 

 seventh abdominal segment almost wholly yellow scaled, etc. Head 

 l)lack, oral margin and base of antennas yellow, remainder of antennae and 

 the proboscis black, palpi brown, its scales chiefly concolorous, no cluster 

 of white hairs or scales at their apices ; narrow scales of middle of occiput 

 golden yellow, the upright ones chiefly black, sides of occiput covered 

 with depressed whitish scales and with a small cluster of black ones ; 

 thorax reddish brown, scales of mesonotum golden yellow, becoming pale 

 yellow in front of the scutellum and on the pleura ; abdomen black, its 

 scales black, except a crossband of yellowish white ones at base of each 

 segment, the bands considerably narrowed at the middle, similar scales 

 scattered over the sixth and nearly the whole of the seventh segment and 

 along apices of the two preceding segments ; legs yellow baeally, becom- 

 ing brown on the tibic^ and tarsi, scales of femora chiefly pale yellow, of 

 the tibiae mostly black, those on the hind side pale yellow, on the bases 

 of the tarsal joints whitish, those on the second joint of the hind tarsi cov- 

 ering about one-fourth the length of the joint, front tarsal claws toothed ; 

 wings hyaline, lateral scales of the veins long and narrow, hind crossvein 

 nearly its length from the small crossvein, petiole of first submarginal cell 

 from one-half to four-fifths as long as the cell; length, 4 mm. One speci- 

 men bred May 6, by Mr. LaRue Holmes. 



Habitat. — Summit, New Jersey. 



I have also examined 8 females and as many males, bred by Prof. J. 

 B. Smith, from the salt-marshes of New Jersey. In the male the scales of 

 the palpi are black, those of the under side and at bases of the last two 

 joints yellowish white, no whitish band at base of the antepenult joint. 



Prof Smith informs me that the larva is readily separated from that 

 of sylvestris. 



Ciilex auri/er, new species. — Female. Near triseriatus, but the 

 scales on sides of mesonotum golden yellow instead of white, and the 

 venter is without crossbands of black scales. Black, the halteres, coxte 

 and femora largely yellow ; scales and hairs of palpi brown, scales of occi- 

 put golden yellow, the upright ones brown ; scales in middle of mesono- 

 tum brownish black, those on the sides and many in front of the scutellum 

 golden yellow, those of pleura pale yellow ; scales of abdomen black, those 

 on the venter pale yellow, sometimes encroaching a trifle on the dorsum,
