UHLER ON INSECTS. 39^ 



Sceloporus, Cnemidojjhorus, etc., are sharp-sighted and ready, and doubt- 

 less the pattern of marking and colors are just such as to place it 

 in closest harmony with its surroundings. It is not unknown in Kan- 

 sas, and all the specimens that I have yet seen from that State are 

 larger than those from Eastern Colorado; while others from New Mexico 

 and Arizona have been large, like those from the vicinity of Laramie. 



PoDisus Stal. 



1. P. modestus.

A few specimens were swept by me from bushes in Beaver Brook 

 Gulch and in Clear Creek Caiion during the early part of August. The 

 sjjecimens were of the usual pale yellow color, marked and punctate with 

 red, and with the black vitta of the membrane and spDts of the con- 

 nexivum clearly defined and very apparent. 



2. r. S2)inosus.

One specimen from near Pueblo, Colo. This region near the Arkan- 

 sas River, except in its alkaline soil, resembles the river-bottoms and 

 lowlands adjacent to creeks in the country southeast of Baltimore. 

 The first insects that I there saw flying, and most of those which I swept 

 from the bushes and plants, were such as I was accustomed to find com- 

 mon near my home ; but away from the vine-clad river-bed, the fauna 

 was quite different. There the Sunflowers, Mentzelias, Euphorbias, and 

 other flowers of the plains, yielded another set of insects; and although 

 many of these were different from those I had found near Denver, yet 

 some of the same kinds were present, of such forms as were the most 

 widely distributed. 



This species did not occur on the plains proper, but was swept from 

 a bush in the bed of the riv^er, at a point where there had been an over- 

 flow into a depression of the surface. 



LiOTROPis, new genus. 



Broad-oval; the pronotum wide and gently sloping toward the ante- 

 rior margins, with the lateral angles wide and lobate. Head depressed, 

 narrow ; the lateral lobes almost lamellar, separated by a cleft in front 

 ofthetylus; tylus acute at tip, much shorter than the lateral lobes; 

 ocelli placed near the eyes and behind the line of their base ; antennae 

 slender, the basal joint not reaching the tip of the head, the second 

 joint shorter, and the third very much longer than either of the others. 

 Buccula3 very narrow, a little shorter than the head, sinuated at base ; 

 rostrum starting at the base of the lamellar cheeks, slender, not broadly 

 depressed, the basal joint inclosed by the bucculfc ; second joint slender, 

 a little compressed, longest, reaching to the base of the prosternum ;
