TRIMEROTROPIS TESSELATA, new species. 

 Trunerotropiti coeruleipcs TowsHEND, In.s. Life, VI, 1893, \>. 31. 



Similar to Trimerotropis^ caeraleipex in the structure of the head and 

 ])r()notum and very closely related to it. The following- points of dif- 

 ference may serve to disting-uish it. 



Size medium, with unusually slender teg-mina and wings; coloi*. ash 

 with a slight suHusion of brown on the top of the head and pronotum, 

 and base of the tegmina much and strongl)" varied with fuscous. 



Head as in that species, except that the vertex is more prominent, 

 forming a right angle (seen from the side) with the front, the tip of 

 the angle slightly rounded instead of a decidedh^ obtuse angular^ Pro- 

 notum with the process of the metazone ver}^ strongly obtuse angulate, 

 with the margins straight and the tip sharp. Tegmina very long and 

 slender and decidedly falcate at the tip, cinereous, with very conspicu- 

 ous fuscous bands at the end of the first, second, and thiixl (|uarters. 

 each of these solid and well delined on the anterior and middl(> lield. 

 punctate on the posterior field; beyond the third fuscous band is a 

 series of large, distinct, triangular spots on either margin. Avith a very 

 few" equally distinct and well-detined spots in the middle area; light 

 1 lands unspotted, except the basal one, which has a few fuscous punc- 

 tations; radial sector with its last branch not more distant from the 

 fork than a third (male) of the length of the sector. Wings long and 

 narrow, the length slightly exceeding twice the width; apex slightly 

 attenuated; disk nearly opaque light green wath a yellowish tinge, 

 with the outer half entirely infuscated, less deeply prcapically; the 

 fuscous border is continued along the posterior margin a little less than 

 half wa}^ to the anal angle, spur extending distinctly more than half 

 wa}' to the base. Posterior femora with a faint preapical light hand, 

 but the fuscous bands inconspicuous. Hind tiVji* pale blue, w ith the 

 su))basal pale annulus incons[)icuous. 



Length of bod}', male, 21i mm.; length of tegmina, 2-1^ nmi.: 

 length of posterior femora, 12 nmi. 



One male, Turke}" Tanks, Arizona, July 17, Bruner collection. This 

 is the species probabl}^ which is mentioned by Tow^nsend' under the 

 name of coeruleipes. 



TRIMEROTROPIS CALIGNOSA, new species. 



This species is very closely related to the two preceding species, but 

 is strikingly different in color. 



Size, medium; color, very dark fuscous, almost black, except for 

 the well-defined and distinct light bands on the tegmina, and the 

 lighter ground color of the posterior femora. 



Head as in the two preceding species, with the vertex not ({uite so
