REVISION OF ELEODIINT BLAISDELL. 137 



longer than the fifth, the hitter sliahtly longei' than the sixth, the 

 latter and seventh equal. 



Fronotum usually widest at the middle, frequently widest just, 

 in front of the middle. 



Elytra irregularly and quite densely muricately punctate, very 

 minutely so on the dorsum, coarser on the sides and apex ; from each 

 puncture arises a rather short, stifl', curved, inconspicuous and semi- 

 recumbent seta. These are not evident on the inflexed sides. 



Otherwise as in letcheri^ but a little more robust. 



Meas}irements. — Males: Length, 14.5-16 mm.; width, 5-6.5 mm. 

 Females : Length, 15-16 mm. ; width 7.5 mm. 



Genital characters as in letcJieri 



Habitat. — Taken in Modoc County, California, by Dr. E. C. Van 

 Dyke. 



Number of specimens studied, 10. 



Cotypes in my own and Dr. Van Dyke's collection. 



Type-locaFity. — Modoc County, California. 



Diagnostic cliaracters. — In form and sculpturing resembles letcheri, 

 but the surface is smoother and more shining. The elytra are not 

 ]3ubescent. 



Prosternum more or less strongly convex antero-posteriorly be- 

 tween the coxa?, compressed and vertically truncate as in letf-heri^ or 

 with a more or less developed nuicro, which is at times feebly deflexed. 



Mesosternum as in letcheri. 



This form is not in the LeConte collection (Blanchard). 



Tarsal formula : 



Pro. Meso. Meta. Metatibiie. 



Male.— 2i 3 3§ 6 



Female.— 2 3 3i 6 



In the U. S. National Museum collection there is a very interesting 

 series of this species taken at The Dalles, Oregon, July, by Hubbard 

 and Schwarz ; the heterotypes are very much smaller but the series 

 lead directly up to the typical form of nandykei The genital char- 

 acters are those of the present subgenus. This small form may be 

 characterized as follows: 



Forma parvula. — Small, ovate. Pronotum quadrate, strongly and 

 quite semi- circularly convex from side to side; sides feebly and quite 

 evenly arcuate: apex truncate in circular arc. with angles rectangular; 

 base truncate, angles subrectangular. Elytra distinctly asperate with 

 muricate granules, densely placed and in somewhat evident longitu- 

 dinal series when viewed antero-posteriorly, more or less transversely 

 rugulose laterally; humeri acute and feebly prominent anteriorly. 



Antennae in the male long, reaching beyond the prothoracic base, 

 scarcely compressed and somewhat incrassate externally.
