A Monograph of Culicidae. 



Abdomen as in the J . Legs banded as in the $? , but the 

 pale basal bands more of a yellow hue. 



Fork-cells very small ; first sub-marginal cell a little longer 

 and much narrower than the second posterior, its base a little the 

 nearer the apex of the wing, its stem a little longer than the cell ; 

 stem of the second posterior cell also longer than the cell ; 

 posterior cross-vein about one and a half times its own length 

 distant from the mid. 



Fore and mid ungues unequal, both uniserrated, the larger 

 mid ungues rather straighter than the much curved fore ones ; 

 hind ungues equal, prominently uniserrated. Basal lobes of 

 genitalia very hairy, claspers narrow, thin, terminating in a 

 longish spine. 



Length. — 4*5 to 5 mm. 



Habitat. — Pecos Canon, New Mexico, U.S.A. 



Time of capture. — June 16th to 29th. 



Observations. — A very abundant species, according to Dr. 

 Grabham, caught after sunset. It varies very much in size, the 

 smallest specimen being 4 mm., the largest 5 * 5 mm. The $ has 

 evidently a variable adornment on the thorax, and is peculiar in 

 having the hind ungues uniserrated. 



The species can easily be told from any other Grabhamia with 

 banded legs by the basally-banded abdomen and last hind tarsal 

 being black and by the white-scaled sub-costal and first long vein. 

 <?. dorsalis, which it most nearly approaches, has the abdomen 

 and thorax with different adornment and the legs basally and 

 apically banded, not basally as in this species. 



The type is in the British Museum (Nat. Hist.). 



The larva. — Head deep chestnut brown, eyes black, reniform, 

 pale around ; antennae pale testaceous at the base, dark at the 

 apex, terminating in two small spines and a third larger flattish 

 pointed one, paler in colour; there is also a long lateral spine 

 about half way down the antenna ; mouth whorls bright golden- 

 yellow \ thorax and abdomen pale brown with a double darker 

 dorsal line, the front of the thorax with four tufts of black hairs 

 in the middle in front, then two separate hairs and then another 

 tuft on each side, two pairs of long lateral tufts, the first pair 

 with two single black bristles just behind them and a little more 

 centrally placed ; the first two abdominal segments with large 

 lateral tufts, remainder with small ones ; siphon short and thick, 

 deep brown, about as long as the penultimate and antepenulti- 

 mate segments ; a few tufts of hair near its base and also a patch
