concave front and basally impressed pronotum, among other 

 features. 



Homalota lepidula n. sp. Slender and subparallel but not quite as 

 depressed as usual, alutaceous, blackish-piceous, the elytra a little paler, 

 dark brown, blackish basally, the head and abdomen black, the legs 

 dark brown; punctures fine and indistinct, a little less so on the head as 

 usual, fine and sparse on the more shining abdomen but denser basally; 

 pubescence not conspicuous; head and antennae throughout nearly as in 

 humilis, except that the former is only about three-fourths as wide as the 

 prothorax, with the front wholly unimpressed; prothorax larger and less 

 depressed than usual, fully a third wider than long, the outline nearly as 

 in the preceding, except that the sides posteriorly are only very feebly 

 convergent, barely becoming straight basally, the angles obtuse and 

 slightly rounded, not in the least prominent, the surface very faintly 

 impressed at base medially; elytra almost as long as wide, with feebly 

 diverging sides, the humeral parts unusually prominent longitudinally 

 above the flanks, at base only very little wider, the suture two-fifths 

 longer, than the prothorax; abdomen linear, narrow, very much narrower 

 than the elytra, the four impressions moderate and gradually feebler, 

 the fifth (cf) fully one-half longer than the fourth. and with a small and 

 very feeble longitudinal tumidity at the hind margin medially, the sixth 

 with its flat surface depressed below the sides, from which it is separated 

 by thin elevated cariniform walls, which curve inward posteriorly, their 

 slightly prominent apices limiting laterally the somewhat narrowly 

 truncate and but finely and feebly reflexed apex of the segment, the flat 

 surface with the elongate asperities unusually thin, carinuliform and well 

 separated. Length 1.85 mm.; width 0.38 mm. Texas (Houston). 



A very small species, allied somewhat to the much larger funesta 

 and fiexibilis in the general nature of the sexual characters, but 

 differing in the more feeble basal narrowing of the prothorax, with 

 the angles obtusely blunt or slightly rounded and not at all promi- 

 nent or everted, as they are in those species; also in having a feeble 

 apical carinule on the fifth tergite of the male and in the rather less 

 depressed upper surface of the head and prothorax. 



Amenusa Csy. 



With a general external facies strongly recalling Homalota, 

 this genus differs radically in having the middle coxse widely sepa- 

 rated, the long flat truncate metasternal projection abutting closely 

 against the broad apex of the mesosternal process; also in having 

 only three of the abdominal tergites impressed at base. The surface 

 of the body is less depressed, although the dense sculpture and the 

 coloration are almost similar. Mr. Fall sent me many years ago
