CALOSPASTA, Lee. 

 Calospastanemognathoides, n. sp.— Body black, moderately shining. Thorax 

 rufous. Head black, shining, scarcely punctured. Thorax rufous, sub-quadrate, 

 sides moderately rounded, feebly narrower in front ; disc moderately convex, 

 shining with very fine punctures. Elytra at base one half broader than the 

 thorax, broader behind the middle, scabrous, black. Body beneath black, 

 shining and with few short yellowish hairs, abdomen sub-opaque. Legs black, 

 shining, sparsely but coarsely punctured and with few yellowish hairs. Length 

 .36 inch ; 9 mm. 



Resembles JSfemognatha atripennis, Lee, in appearance. The tarsal 

 claws are as in C. elegans, Lee, the two portions of each claw connate, 

 the under shorter than the upper. The antennae are as in 0. elegans. 

 The surface has been entirely deprived of pubescence. 

 One female from Owen's Valley, Cal. 



C. perpulchra, n. sp. — Shining blue, elytra with a large humeral spot, median 

 transverse band and sub-apical yellow spot. Head coarsely but sparsely punc- 

 tured. Thorax longer than broad, narrowing in front, sides behind the middle 

 sub-parallel ; disc moderately convex, shining, coarsely but sparsely punctured. 

 Elytra nearly twice broader than thorax, parallel, scabrous, moderately convex, 

 sparsely clothed with yellowish hairs. Beneath bluish, shining, sparsely 

 clothed with short yellowish hairs. Length .28— .40 inch, 7—10 mm. 



This species varies greatly in its markings. One specimen in my 

 cabinet is entirely blue ; two have the humeri alone yellow ; the 

 greater number have a humeral space and irregular transverse band 

 behind the middle yellow, not attaining either suture or margin, others 

 have a sub-apical spot in addition. The sculpture of the front varies 

 considerably. In some specimens the surface is irregular without any 

 definite formation of ridges or depressions; one specimen has a moder- 

 ately convex and prominent tubercle within the insertion of the 

 antennae; others again have a broad median groove bounded by a 

 ridge on each side and a smaller tubercle within the insertion of the 

 antenna, limited within by a slight groove. This species may be dis- 

 tinguished from any varieties of elegans by the more elongate thorax, 

 surface more shining and very much less densely pubescent. 



Collected in Owen's Valley, and Posey Flat (S. E. Sierra region) 



California. 



In the males the front is deeply grooved at middle with a prominent 



tubercle within the base of the antennae, the basal joints of the anterior 



tarsi are also distinctly dilated.

Specimens in my cabinet from Cariso Creek have the yellow vitta 

 of the elytra shortened so as to become merely a humeral elongate spot
