REVISION OP THE TENEBRIONIDJ! OF AMERICA, 



N. oarinata, Lee, Ann. Lye. 5-138. 



Differs from the two preceding in the absence of thoracic foveas and in the elytral 

 sculpture. In this species the elytral costae are alternately continuous and interrupted, 

 the former 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. sequicollis, Escli., loc. cit. 



The head is not cristate, the thorax not fovcate, 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 CRYPTOGLOSSINI. 



Labriun almost entirely concealed. Eyes reniforrn, not coarsely granulated. Mentum 

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

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

 ous. Tibiae 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 ; 



antennae scarcely flattened. centrioh'era. 



Last joint of antennae truncate, much smaller than preceding joint ; 



antenna 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 C. spiculifera, are in my cabinet, with almost entirely smooth thighs, while spe- 

 cimens of Oochila have thighs with rather coarse grannies. 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.

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

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

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

 Presternum produced behind the coxae.
