Abuudant near Fort Union. New Me:Sico. On account of the pe- 

 culiar marking- of the elytra I at first supposed it to belong- to Tct,-<i- 

 ovyx^ but on examination found it to possess all the characters of a <re- 

 nuine Ejjicauta. The thorax is more robust than usual, being about 

 one-third wider than its length; the two rounded black spots are so 

 large as nearly to meet on the median Hue. 



I desire in the name of this eieaant species to commemorate the 

 friendly assistance rendered to us in our scientific pursuits by Capt. 

 Lyman Stuart, late Commissary of Subsistence, U. S. V., a member 

 of the expedition. We are indebted to him for a series of specimens 

 collected in the ujiper part of the Uio (Iraiide Valley. (>n the road 

 from Fort Garland to Santa Fe. 



TOPOSCOPTJS Lee. (n. g. Rhipiphorida;.) 



The single species of this genus represents on this continent the 

 rare Evaniocera Diifourii Latr., of Hungary, and agrees with that 

 species in size, form and sculpture, so closely that without examination 

 it would not be readily distinguished. 



The generic differences are, however, very great, the chief ones 

 being as follows : 



The vertex is less elevated than in Evaniocera ; the ei/ea are divide.tl 

 into fvo portions, connected by a slender ]me of smooth corneous ma- 

 terial, which is destitute of lenses, while in Evaniocera they fire only 

 deeply emarginate. 



The 3d joint of the antennae of the male is longer, with a basal 

 process about foui'-fifths as long as the processes of the following 

 joints, while iu Evaniocera the 3d joint is short, prolonged externally 

 into a process one-fifth as long as those of the following joints. 



The side margin of the prothorax is more developed, extending from 

 the hind angles nearly to the apex. 



The claws are not finely pectinate, as in Eoa7iioce.ra, but bifid at tip, 

 and armed with three slight teeth, somewhat as in Ancholmmus Gerst.
