NORTH OF MEXICO. 34'? 



ined, margin slightly reflexed, hind angles distinct, disc modern! .. Elytra oval, 



slightly emargiuate at base, humeri distinct, elytra! margin distinct, slightlj reflexed. Surface finely and spa 

 punctured. 



The he. m1 and thorax are much more opaqu i than the elytra. The thorax is narrower 

 than the elytra, and has a slight median depression near the base. The sides of the elytra 

 are very feebly rounded and are almost sub-parallel, the apex is nol prolonged. The up- 

 per surface of the bod) is P ravex, the under surface paler in color and more sliii 



Length .33 inch.

ported on a very short broadgular peduncle. Ligula ti slightly e i basal membrau 



visible, palpi short, last joint flattened, conical, longer than ling. Maxillary palpi long, last three joints 



sub-equal, conical, the terminal slightly flattened. Labium transverse, partly concealed. Mead i broad, 



feebly emarginate and distant fr the thorax. Front hemi-hexagoiial, feebly converging in front, anteriorly broadly 



emargiuate, suture in listinct. Antenna! longer than the head and thorax, slender; first two joints short, third 1 • 



quailing the third and fourth together, joints four to ten gradually decreasing, last joint longer and p tinted 

 at tii in oval. Elytra broader at base than the thorax, humeri distill entire, narrow and 



horizontal. Troi if middle coxae distinct. Mctastemu tdomen tri- 



angular. Li gs slender, tarsi long, sparsely clothed with short spinous hairs. hind tarsi longer than the

This genus lias proved the mosi troublesome of any of I s lera to which 1 have 

 been required to assign a place. 



The hind margins of the third and fourth ventral segments do not exhibit in so marked 

 a degree the coriac :ous margin, which has been taken as the charact r dividing the family 

 into two sections, and it is only with some difficulty, or by the undn i protrusion of th • 

 terminal segments, that the membrane connecting them be* om - visible. In outline the

There are. however, no other affinities between this insect and the Epitragini, as will be 

 seen by the smaller mentum, the middle trochantin and the form of the head. The pro- 

 sternum is deflexed behind, and the mesosternum oblique. This genus and the preceding, 

 in an arrangement of the g t large, should in all probability constitute n tribe bj 



themselves, near the Goniaclerides ol South America, though abundantly distinct by m 

 characters. From Alsephus this genus maj be known by the form of in mtum and gular 

 peduncle, by the margins of the Iron' not being reflexed and by the form ol the antenna-.
