C. iilConMplcua, n. sp. — Head black, moderately coarsely butsparsel 

 punctured. Anteniire ^ subserrate, entirely black. Thorax rufous, sparpal 

 punctured. Elytra black, sparsely and moderately coarsely punctured, aui 

 sparsely pubescent. Body beneath and le^s black. Length .20 — .26 inch; 

 i — 0.5 ram. 



Male. — Elytra at tip black, neither smooth, elevated nor impressed. 



Female. — Elytra resembling the male. 



Kesoinbles coUarls from the Atiautic Region which, however, has 

 the elytra of male at tip somewhat smoother and distinctly impressed. 

 Collected in California and presented by Mr. P. S. Sprague, of 

 Boston. 



C. Bardii, n.sp. — Head black, front sparsely, hind angles coarsely and 

 densely piuu-tured. Antennae black, subserrate. Thorax rufous very sparsely 

 punctate. Elytra black, with oblique, narrow, testaceous stripe from the 

 humerus to the apex, surface coarsely and deeply and not densely punctured, 

 lioily beneath and leg? black. Length .22 inch; 5.5 mm. 



J/«i/e.--Tip of elytra testaceous, prolonged and turned slightly upward. 



Female. — Elytra normal at tip. 



Collected by Mr. Crotch, at San Buenaventura, California ; dedi- 

 cated to Mr. Thoujas Bard, of that region. 



Vj. distingiienda, n. sp. — Closely allied to the preceding species and 

 agreeing witli it in form and sculpture and and differs only in the elytra beinj; 

 entirely black (except at tip %) without oblique vitta. Length .22 inch; 

 5.5 mm. 



Collected at San Buenaventura, California. 



These two species, Bardii and dLstinguenda, differ from all the 

 other species in having the elytra caudate in the male. The pro- 

 longation is acute and turned slightly upward and inward. 



The species of Corphyra may be taken in considerable numbers, at 

 times, on the flowers of various umbelliferous plants.
