3i8 MEMOIRS ON THE COLEOPTERA 



metallic; legs obscure rufous, the femora still somewhat more obscure; 

 head but little more than half as wide as the prothorax, the eyes 

 not so large as in the two preceding and only moderately prominent; 

 antennae stouter, extending barely to the thoracic base; prothorax 

 large, barely two-fifths wider than long, the sides parallel and nearly 

 straight, rapidly rounding before the middle; basal angles right; 

 apex more than two-thirds as wide as the base, very feebly sinuate, 

 almost truncate, the angles broadly blunt; impressions obsolete; 

 foveal region virtually impunctate, the inner fovea long, feebly im- 

 pressed, its anterior part deeper, the outer fovea small, subobsolete; 

 elytra slightly less than one-half longer than wide, just visibly wider 

 than the prothorax, more rapidly and obtusely rounded behind than 

 in the two preceding; stria? rather fine but sharply defined, minutely 

 punctulate, the scutellar oblique, not free, joining the second well 

 behind the base; intervals flat. Length (?) 6.7 mm.; width 3.0 

 mm. Arizona (locality unrecorded) profuga n. sp. 



Besides afoveolata* there are two other species without the ocel- 

 late subscutellar puncture, as shown above. The species described 

 by Horn under the name belfragei, is very distinct in its entirely 

 pale antennae; it is from Texas and I have seen no representative, 

 but the radically different antennae may betoken other striking dif- 

 ferential characters. The value of the presence or absence of the 

 ocellate subscutellar puncture is assumed to be primary, as in the 

 second group of Amara, but in one example of scitula at hand, there 

 is a full development of this puncture on the right elytron, but no 

 vestige of it on the left. 



The species described as depressa by LeConte (Ann. Lye., N. Y., 

 1848, p. 365) is not mentioned by Horn in his short revision of 

 Tricena, but Hayward places it as a synonym of pallipes. This is 

 highly improbable, because of its less pronounced convexity and 

 other reasons. I should have been disposed to identify shermani 

 as depressa, in spite of several important incongruities, were it not 

 for the fact that the seventh elytral stria is said to have five posterior 

 punctures in the latter; there are only two feeble subpunctiform 

 subapical enlargements of the seventh stria in shermani. If the 

 type of depressa be still in existence, it should be restudied, for it is 

 a distinct species, apparently without doubt possibly, however, a 

 small Triplectrus; this possibility is at least surmisable from the 

 description. 



* It is unfortunate that the author was not able to alter this name to harmonize with 

 philologic principles; its present form, as a combination of Greek and Latin, cannot be 

 approved, and yet there is no way to change it under accepted rules.
