27H REVISION OF THE TEXERRIOXID.E OF AMERICA, 



V carinata, Lee, Ann. Lyo. 5 138. • 



Differs from the two preceding in the absence of thoracic foveae and in the elytra! 

 sculpture. In this species the elytral costa? arc alternately continuous and interrupted, 

 the tinnier being higher and crenulate, the latter merely rows of small elevations between 

 the higher costa*. 



Not rare in Southern California (Tejon. San Pedro and San Diego). 



Length .50— .62 inch. 



N. ssquicollis, Bsch., loc. cit. 



The head is not cristate, the thorax not foveate, and the elytra ornamented with rows 

 of elongated tubercles less prominent than in any of. the preceding species. Not rare at 

 San Francisco and Tejon. 



Length .50 inch. 



TRIBE XIII CRYPTOGEOSSINI. 



Labrurn almost entirely concealed. Eyes reniform, not coarsely granulated. Mentum 

 moderately large, supported by a broad gular peduncle, exposing maxillae and concealing 

 ligula. Elytra with narrow epipleurae and moderately embracing the body. Body apter- 

 ous. Tibia? with moderately long, slender spurs. Tarsi spinous beneath. 

 The genera of this tribe are two in number, and differ as follows : 

 Last joint of antennae oval, acute, scarcely smaller than preceding joint ; 



antenna? scarcely flattened. centrioptera. 



Last joint of antenna? truncate, much smaller than preceding joint ; 



antenme strongly flattened. cryptoglossa. 



I have found it necessary, owing to the discovery of new species, to annex the genus 

 Oochila, Lee, to Centrioptera, the form of mesosternum being a character of scarcely any 

 value in this genus, and the denticulation of the hind thighs of still less; specimens un- 

 doubtedly ('. spiculifera, are in my cabinet, with almost entirely smooth thighs, while spe- 

 cimens of Oochila have thighs with rather coarse granules. The degree of rugosity or 

 spiculation of the elytra at its sides, appears to determine the presence or absence of the 

 femoral denticulations, and is consequently not even of specific value. 



CENTRIOPTERA, Mann. 



.Mann. Bull. Mosc. is!:;, p. 249. Oochila, I Class. Col. X. A., p. 220. Asbolus (part) Lee. 



For convenience in recognising our species I add the following table: 

 Elytra with scries of more or less evident tubercles becoming spiculate at the sides near 

 apex. Hind thighs within more or less denticulate or granulate. 

 Prosternum produced behind the coxae.
