our faunal limits, the dorsata of Say so referred by Dury 

 having been properly removed and made the type of a new 

 genus by Mr. Schaeffer. The species of Neobrotica are nu- 

 merous in Mexico, and are very similar in general appear- 

 ance to Diabrotica, differing by their appendiculate claws and 

 usually strongly transversely impressed prothorax. Pluris- 

 ticta appears to be most nearly related to semicostata Jac. by 

 its elytral sculpture, but the latter is unspotted ; the very 

 brief description of Jacoby does not, however, permit a 

 proper comparison. 



LUPERODES Mots. 

 L. marginalis. 



Pale yellow, head a little darker, lateral reflexed margin of pro- 

 thorax and the sutural and lateral margin of elytra narrowly piceous, 

 the sutural shade more or less evidently diffusedly dilated before the 

 middle ; three or four basal joints of antenna; pale, the following joints 

 piceous except at base ; body beneath piceous ; legs entirely pale. 

 Upper surface strongly shining, the head finely alutaceous and duller ; 

 punctuation moderately distinct and fairly close. Length 3 mm. 



Alpine, Texas (Wickham). 



With the exception of coloration, this species agrees very 

 closely with varicornis, having as in that species joints 2-3 

 of the antennas subequal and together not longer than the 

 fourth, and the basal joint of the hind tarsi very evidently- 

 longer than the entire remainder ; the sexual characters are 

 also as in varicornis. In one example, which is evidently 

 immature, the elytra lack the dark margin, and the body 

 beneath is entirely pale ; the narrow fuscous edge of the 

 prothorax is, however, evident. According to the descrip- 

 tion of both LeConte and Horn varicornis is always entirely 

 yellow, or at least of uniform shade above. 



Li. atricornis n. sp. 



Oblong, moderately elongate, head brown, prothorax entirely yel- 

 low, antenna;, legs and metasternum black, abdomen paler. Upper 

 surface polished throughout, the head with a few fine punctures pos- 

 teriorly, prothorax scarcely visibly punctulate, elytra finely rather 

 closely punctate. Antennae fully two-thirds as long as the body, 

 second joint a trifle longer than the third, the two together as long as 

 the fourth. Front broadly convex, not at all carinate between the
