REVISION OF ELEODIINI BLAISDELL. • 283 



produced in the male; scarcely produced and obtuse in llie female. 

 Legs long and rather stout. 



Measure fiioitti. — Males: Length, 24.5-34: mm.; width, 9-10 mm. 

 Females: Length, 2G-32 mm.; width, 10.5-10.5 rn.n. 



Forma minor. — Somewhat robust and more or less shining. Inter- 

 stitial punctures quite distant and very' distinctly prickly laterally 

 and on the apex. Sexes quite homomorphic. Elytral apex scarcely 

 produced and more or less abtuse. Legs moderate. 



Measurements. — Males: Length, 22.5-27 mm.; width. 8-9.5 mm. 

 Females: l^&ngih^ 21,5-26.5 mm.; width, 9.2-8.5 mm. 



Habitat. — Forma typica. — California (San Diego County, Los 

 Angeles County; collections Charles Fuchs, E. C. Van Dyke, F. E. 

 Blaisdell, and U. S. National Museum; Fort Tejon, April 19-21, 

 Fuchs iind Hopping) ; St. Nicholas Island (collection U. S. National 

 Museum). 



Forma minor. — California (l*oway, elevation 700 feet, F. E. Blais- 

 dell ; Fort Tejon, Fuchs and H()i)ping: collection U. S. National 

 Musemn). 



Number of specimens studied, 125. 



Type in the LeConte collection. 



Type-locality. — San Diego, California. 



Salient type-characters. — Thorax broad, sides greatly rounded and 

 subdepressed ; narrowed behind ; basal angles rectangular, somewhat 

 unusually prominent; anterior angles acuminate. Elytra finely and 

 seriateh' punctate; apex declivous^ attenuated (LeConte). 



Diagnostic characters. — This race is separated from acuticauda by 

 the form of the pronotum, elytral apices, and sculpturing. 



Acuticauda has the pronotum very narrowly granulate and very 

 feeblj^ impressed laterally along the margin ; the disc is nearly evenly 

 convex from side to side; in laticollis the sides are quite broadly 

 impressed and granulate; consequently the surface is less evenly and 

 less strongly convex. 



In acuticauda the punctuation is simple, while laticollis is remark- 

 able for having the interstitial punctures very finely muricate; on 

 the elytra laterally the interstitial punctures are distinctly prickly, 

 on the apex irregular and likewise muricate. 



In laticollis the elytra are never caudately produced, although at 

 times somewhat gradually narrowed, but never as strongly as in 

 acuticauda. 



Deutipes forma elongata'nvAj have the pronotum somewhat im- 

 pressed laterally and more or less granulate, but here the form'^of the 

 prothorax must be the diagnostic criterion. (See acuticauda and 

 synopsis.)
