MEMOIRS ON THE COLEOPTERA 



type but with notably large and rather prominent eyes, the length 

 of which is greater than a third of the frontal width between them; 

 prothorax one-half wider than long, about equally wide at base and 

 apex, the parallel sides slightly rounded anteriorly, just visibly sinu- 

 ate basally, the angles sharp and very feebly everted; lateral gutter 

 deep and even throughout, the inner bounding carina half as long 

 as the pronotum, the anterior part of the margin also rather acute 

 though not cariniform; surface and stria nearly as in the preceding, 

 the subbasal sulcus not medially interrupted; elytra more than one- 

 half longer than wide, two-fifths wider than the prothorax, rounded 

 in apical third, broadly subtruncate at apex, parallel, with slightly 

 arcuate and rather widely reflexed sides and somewhat narrowly 

 rounded humeri; there are two evident and feebly punctulate striae, 

 the others obsolete, the series of minute interstrial punctures sub- 

 obsolete, barely traceable; fovese nearly as in flavicauda, the anterior, 

 however, much coarser. Length 1.65 mm.; width 0.6 mm. Guate- 

 mala (Quirigua), Mrs. T. D. A. Cockerell *ocularis n. sp. 



The sutural stria in the genus becomes feebler posteriorly and does 

 not quite attain the apex, the latter not beaded as it is in Tachyta, 

 but, externally, the usual recurvature as visible in Tachyta, 

 still persists and is moderately long. The extended distribution 

 of flavicauda is altogether exceptional in the subfamily; the Pacific 

 coast representatives offer no essential differential features that I 

 can observe; individuals are extremely uniform in size throughout 

 its range. 



The following species are unknown to me in nature; possibly 

 some of them may have been unknowingly redescribed in the fore- 

 going pages, but of this nothing definite can be said at present:
