SUPPLEMENT TO PSYCHE. 



[April 1896. 



Abdomen distinctly punctured, but first seg- 

 ment shining, with the punctures sparse, 

 lateral hind margin of first segment with 

 a narrow hair-band. 



Hab. — Colorado; Chamber's Lake, Lari- 

 mer Co., July iS, 1S95, 9500 feet (C. F. 

 Baker). Also from New Mexico; Ruidoso 

 Creek, 750ofeet, July 6, 1S95, on Scrophularia 

 (E. O. Wooton, 75). Differs from trideiis by 

 its smaller size, clearer wings, second sub- 

 marginal cell broader in proportion to its 

 length, tubercles with a black dot. and 

 less deeply punctured first segment of 

 abdomen; from ver/iculis liy the first 

 recurrent nervure entering the second sub- 

 marginal cell, and the shorter antennae; 

 from mesillae by its larger size, longer 

 and narrowed lateral face-marks, etc. ; from 

 pygtnaea by its larger size, the face-marks, 

 etc. ; from digitafits by the clearer wings, 

 and the curved, instead of straight, lateral 

 face-marks. 



Prosapis rugosulus, n. sp. — J about 

 6 mm. long, black with orange markings, 

 head and thorax strongly punctured, scutel- 

 lum with the punctures larger and sparser 

 than those of the mesothorax. Head of 

 ordinary size, face only moderately nar- 

 rowed below, vertex confluently punctured, 

 antennae wholly dark, scape stout. Face 

 below antennae reddish-orange (perhaps 

 yellow, altered by cyanide), median pro- 

 jection short, broad, truncate; lateial 

 extensions of the pale color rather broad, 

 somewhat excavated b\' the antennal sockets, 

 ending, about on a level with the middle 

 of the scape in a bi'oad truncation. 



Prothorax with a couple of small orange 

 spots on hind liorder; tulierclcs largely 

 orange, with no black .^pot. Tegulae with a 

 small light spot. Pleura rather closely punc- 

 tured. Base of metathorax rugose. Wings 

 grayish hyaline. Femora black. Tibiae 

 black, anterior tibiae orange in front, 

 middle tibiae with a little orange at apex 

 and base, hind tibiae with the basal two- 

 fifths orange. First segment of abdomen 



distinctly and rather closely punctured, 

 first three segments with narrow lateral 

 apical hair- bands. 



Hab. — Colorado; Chamber's Lake, Lari- 

 mer Co., July 18. 1895, 9500 feet (C. F. 

 Baker). 



Var. y(;//«.v, V. nov. J. Tegulae with no 

 light spot; no light spots on hind border 

 of prothorax; lateral face-marks at ends 

 curved inwards, receding a little from the 

 orbital margin. 



Hab. — Colorado; same locality and date 

 as type (Baker). Another form, perhaps 

 a distinct species, differs by the pale mark- 

 ings being yellow, the puncturing of meso- 

 thorax finer, and the scutellum more closely 

 punctured. It is from Steamboat Springs, 

 Colo., 6000 feet (Baker). 



Prosapis tridens, n. sp. — J 6 mm. long, 

 black with reddish-fellow markings. Head, 

 thorax and abdomen strongly punctured. 

 Head of ordinary size, face only moderately 

 narrowed below. Face below antennal sockets 

 reddish-yellow, the clypeal sutures dark; the 

 light color extends upwards in the median 

 line as a conical projection, truncate about 

 the level of the upper margin of the antennal 

 sockets; at the sides it extends upwards as a 

 narrow curved projection reaching the same 

 level, receding from the orbital margin 

 rather slowly, with its concave side follow- 

 ing the margin of the antennal socket. Ver- 

 tex closely and roughly punctured. Antennae 

 wholly dark, their tips reaching only a little 

 beyond the tegulae; scape moderately swol- 

 len. Prothorax all dark except the usual 

 light spot on tubercles, which exhibits no 

 dark dot. Tegulae with a light spot. Meso- 

 thorax moderately shining, very closely 

 punctured, sciitellum not so closely. En- 

 closed portion of metathorax coarsely rugose. 

 Pleura closely punctured. Wings strongly 

 tinged with fuliginous, nervures and stigma 

 piceous. Second submarginal cell not nar- 

 rowed one-half to marginal. Femora black, 

 with a small yellow spot at extreme end; 

 anterior tibiae light in front, middle tibiae
