cause of the more sensibly converging sides posteriorly, the base is 

 actually and relatively much narrower than in linearis; elytra a little 

 shorter, the abdomen similar; linear dimensions almost identical. Cali- 

 fornia (Pomona, Los Angeles Co.). 



The pronotum is feebly concave in more than median third, from 

 before the middle to the base; this impression is however fugitive, 

 and sometimes appears in linearis. I am about convinced that 

 there are two distinct species involved, but will leave the subject 

 as announced above for the present. 



Subgenus Euliusa Csy. 



There is so much general similarity between the species separated 

 generically under this name and those of Gnypeta, that the propriety 

 of uniting them in a subgeneric relationship is sufficiently evident. 



Gnypeta (Euliusa) limatula n. sp. Moderately stout, convex, polished, 

 testaceous-brown in color, the head barely at all darker, the legs pale; 

 punctures minute and everywhere very sparse, not distinctly larger 

 toward the sides of the head; pubescence moderately short, rather coarse, 

 pale; head nearly as long as wide, very nearly as wide as the prothorax, 

 the eyes moderately convex, at a little more than their own length from 

 the base, the tempora forming an evenly converging arc from the eyes 

 to the base; antennae moderately long, pale, slightly infumate and rapidly, 

 somewhat strongly incrassate distally. the second joint as long as the 

 cylindric first but not quite so thick, the third barely evidently shorter, 

 fourth nearly three-fourths longer than wide, the tenth two-fifths wider 

 than long, the last fully as long as the two preceding; prothorax rather 

 small, only very little wider than long, prominently rounded at the sides 

 at two-fifths from the apex, the sides thence strongly convergent and 

 subsinuate medially to the base, the surface feebly impressed medially 

 toward base and with two minute ante-scutellar punctures; elytra mod- 

 erately transverse, about two-fifths wider and a third longer than the 

 prothorax, the humeri well exposed at base; abdomen slightly narrower 

 than the elytra, the sides parallel and very slightly arcuate, the three 

 tergitical impressions deep, rather sharp and smooth. Length 2.5 mm.; 

 width 0.57 mm. Southern California. 



To be placed at the end of the series and identifiable readily by 

 reason of the peculiar form of the head. 



Teliusa Csy. 



The following species is closely allied to alutacea and may prove 

 to be more properly a subspecies. Teliusa appears to be a local 

 development of the Gnypetae, confined to the Rio Grande Valley:
