pale and bright rufous, the antennae dusky rufous, paler toward base; 

 head behind the antennae longer than wide, the sides parallel and 

 straight, the angles broadly rounded and beginning at two lengths ol 

 the eye behind the latter; punctures coarse, deep and moderately close- 

 set toward the sides, nearly as coarse but not quite so close-set beneath 

 throughout, the interspaces not at all strigilate, the flattened post- 

 ocular line distinctly defined, coarsely and closely punctured; antennae 

 rather longer than the head, stout and compact distally, the tenth joint 

 about three-fifths wider than long; prothorax about a third longer than 

 wide, very little narrower than the head, the sides very feebly converg- 

 ing and somewhat uneven, the angles rounded; punctures strong, 

 moderately coarse, the dorsal series of about ten, the sublateral of 7-9,. 

 both rather uneven and with numerous other strong punctures toward 

 the apical angles; elytra barely as long as wide, about equal in length 

 to the prothorax and only slightly wider, the punctures strong bat 

 rather sparse, arranged nearly as in Gyrohypmis hamatut; abdomen 

 minutely, sparsely punctate, more distinctly beneath as usual, very 

 slightly wider than the head. Length 8.0 mm. ; width 1.88 mm. Texas 

 (Austin) texanns n. sp. 



This is one of tiie larger and more conspicuous of our 

 Xantholini, but is unfortunately represented by a single speci- 

 men thus far. 



Lieptacinus Erichs. 



The type of this genus is assumed to be the European 

 parumpunctatus Gyll . , representing a radical departure from 

 the preceding genera of the subtribe Xantholini in having the 

 fourth palpal joint very slender and aciculate ; it differs also 

 in having the oblique ocular, as well as the frontal grooves, 

 long and greatl}' developed and in type of elytral sculpture, 

 the punctures being confusedly aggregated along the suture, 

 but, from the medial series to the extreme lower margin of 

 the flanks, having a linear arrangement. In the preceding 

 genera the elytral punctures are apparently always confused 

 throughout on the deflexed flanks. The pronotal punctures 

 are peculiarly coarse, dee|)ly im[)ressed and always few in 

 number. The flattened longitudinal line behind the lower 

 part of the eyes is nearly as in Gyrohypmis and several other 

 genera, though narrower, but here its lower margin is rendered 

 apparently more prominent by reason of a feebly punctured 

 eroded longitudinal groove at each side of the under surface, 

 and the upper margin is more obtuse and less definite. We
