156 AMERICAN COLEOPTERA. 



vertex, which is more or less rugulose. Prothorax moderately trans- 

 verse, a little narrowed anteriorly, sides arcuate, ante-basal groove 

 broad and shallow on the disk with impressed line at bottom, termi- 

 nating in a fovea at each extremity ; surface finely not closely punc- 

 tate. Elytra punctate as in ignita. Beneath dark cupreous, alutace- 

 ous, moderately punctate. Length 3 mm. 



California; Redondo (type) and Pomona. 



The last ventral of the male is sinuate each side, the lobe 

 rounded, broadly impressed and more shining. Convicta is 

 closely allied to evicta, but the latter is much larger with a 

 polished head, dark antennae, more alutaceous thorax, and 

 with a better marked fovea at the end of the transverse groove. 

 The frontal tubercles in evicta are scarcely at all elevated 

 above the plane of the contiguous vertex. 



H. ovulata n. sp. 



Elongate oval, blue, shining, upper surface finely alutaceous and 

 sparsely finely punctate, the elytral punctures scarcely coarser than 

 those of the prothorax. Antennae piceous, longer than half the body, 

 evidently thickened apically, joints 2-3-4 gradually longer, the fourth 

 three times as long as wide. Eyes not prominent, their width as seen 

 from the front about one-third the interocular width ; frontal tuber- 

 cles rather broad, frontal carina obtuse, vertex smooth. Prothorax 

 unusually elongate, but slightly more than one-fourth wider than long, 

 very little narrowed in front, sides very feebly arcuate, narrowly mar- 

 gined, basal margin bisinuate- each side, basal groove faint. Elytra 

 oval, humeri not prominent, no post-humeral impression. Body 

 beneath dark blue, alutaceous, more coarsely punctate than above. 

 Length, 4.3 mm. ; width, 1.8 mm. 



Canon City, Colorado. 



The unique type is a d 1 having the lobe of the last ventral 

 segment flattened and shining, a little impressed at tip and 

 with a shallow impressed line extending the entire length of 

 the segment. 



By Horn's table this species would fall with tombacina and 

 marevagans because of the apically thickened antennae, and 

 the fourth antennal joint longer than the third. Its more 

 oval form, however, allies it to californica and obliterata. It 

 is much more finely alutaceous and more shining than the 

 latter, and the prothorax is more elongate and the general 

 form narrower than in either ; the prothorax is also much 

 more finely margined than in tombacina, marevagans or obso- 

 leta, being about the same as in californica.
