PSYCHE. 



[March 1 



about as long as wide, inner margin straight, 

 outer margin at the apical two thirds in- 

 curved to the obliquely truncate apex, which 

 is very slightly emarginate. 



This is also a Northern Colorado in- 

 habitant. The three males before me 

 were collected in the foothills west of 

 Fort Collins, Aug. 4th. One of them 

 is slightly larger than the others and 

 distiiictly suftlised with reddish, but it 

 has the peculiar phites of the others. 

 The females are also from the lower 

 foothills, taken May 6th to July aist. 



Atfiysaiiella attenuata n.sp. Brachypter- 

 ous female. Length 5 mm. This species 

 resembles terebrans and curtipemiis and is 

 the largest most robust representative of the 

 genus. Front a twelfth longer than broad, 

 about twice the length of the clypeus. Cly- 

 peus one fourth longer than broad. Vertex 

 very obtusely angulate, transversely de- 

 pressed posteriorly, length at iniddle five- 

 sevenths of width between eyes. Pronotal 

 width twice and a third the length, the latter 

 equalling that of the vertex. 



Color very pale fiflvous, brighter below, 

 tip of ovipositor reddish. Vertex and face 

 with the markings usual to this genus. 

 Pronotal dots subobsolete. Elytra cinereous. 

 Dorsum with indications of lateral lines, and 

 with a double median longitudinal row of 

 black dots; last segment black at base. 



Last ventral segment twice the length of 

 preceding, medially broadly black, the hind 

 margin truncate or very slightly trisinuate. 

 Ovipositor exceeding the pygofers by little 

 less than one-third of its length. 



Brachypterous male. Length 3.25 mm. 

 Darker throughout than the female. Valve 

 longer than the preceding segment, triangu- 

 lar, the apical portion somewhat narrowed. 

 Plates triangular, twice the length of the 

 valve and rather strongly diverging. 



Described from four males and many 

 females collected by myself in Northern 

 Colorado. It occurs at Fort Collins 

 throughout the summer season and I 

 have also taken it at Forrester's Ranch, 

 on the Upper Laramie River on Aug. 

 3rd. 



Athysanella incongrua n. sp. Brachypter- 

 ous male. Length 3.25. Front one seventh 

 longer than broad, a little less than twice 

 the length of the clypeus. Clypeus one 

 fourth longer than broad. Vertex very 

 obtusely' angulate, broadly depressed poste- 

 riorly, length at middle six sevenths of the 

 width between the eyes^ Pronotal width 

 twice and a third the length, the latter less 

 than that of tlie vertex. 



Color very pale fulvous, head, pronotum, 

 and abdomen with a distinct rosy tint, espec- 

 ially on the last. Arcs on front indistinct. 

 Vertex, just before apex, with two small 

 brown closely approximated dashes, one on 

 either side of a white median line; a small 

 black dot on either side of this, near tlie 

 front margin. Pronotum anteriorly with 

 two minute median dots, and three behind 

 each eye. Dorsum with indications of 

 median and lateral lines, each segment with 

 a transverse row of about ten distinct black 

 dots; the last segment blackish at base. Api- 

 cal margins of ventral segments blackened. 



Valve shorter than the preceding segment, 

 broadly rounded, disc dark. Plates about 

 twice length of valve, somewhat diverging, 

 and gradually narrowed to a truncate tip. 



Described from one specimen collected 

 by myself in the foothills west of Fort 

 Collins, Colo., July 2ist. There is no 

 female in my collection with which I 

 can associate this. It somewhat re- 

 sembles the (J of attenuata^ but differs 

 widely in color of head and in genital 

 characters.
