scattered, reddish-brown scales in the middle, gray ones at the sides. 

 Abdomen as in the $. Legs banded as in the $ , but the pale basal 

 bands more of a yellow hue. 



Fork-cells very small ; first submarginal 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 one ; 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 i6thto 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 rnm. 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 the white-scaled sub costal and first long vein. G. 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 antepenultimate segments ; a few
