REVISION OF ELEODIINI BLAISDELL. 203 



Valvvia (Plate 1, fig. 23). — Dorsal plate oblono-, rather narrow, 

 sides strongly reflexed, retracted externally ; external border more or 

 less broadly sinuate, the internal angulate at basal third, and the api- 

 cal margin is more or less truncate and rather prominent at angle, the 

 latter more or less rounded ; surface very deeply concave, finely and 

 very sparsely punctate, setose, setae small. 



Apex short, tip very blunt and not prominent, slightly longer than 

 the appendage, with sparsely placed and short set», without pencil 

 at tip. 



SuJjm.arginal groove not always strongly marked and entirely visi- 

 ble from above; sides of the lateral plate largely visible externally. 



Appendage short, conical, and broadly rounded at tip and not 

 conspicuous; setose, with apical tuft of moderately short hairs. 



Basal proinine'}ices strongly developed. Superior pt^dendal Tnein- 

 hraiie reaching scarcely half way from the base, and with two or 

 three longitudinal grooves. 



Ventrolateral surfaces. — Body quite strongly inflated at base and 

 transversely concave before the apices, strongly so laterally, sparsely 

 setose; apex rather thick — viewed from below. Internal margins of 

 the valves contiguous in about basal third. Genital fissure rather 

 broadly fusiform.

Suturalis. — Number of specimens studied, 50. 



Type destroyed. 



Type-locality apparently not mentioned by Say. 



Salient type-characters. — Reddish-brown along the suture. Thorax 

 with the edge deeply concave in front, lateral margin dilated and 

 reflected; anterior angles with a small excurved point. Elytra 

 scabrous, grooved, lateral edge reflected, slightly elevated and acute
