Chapin — New North American Hydnocera {Col.). 57 



tributed. Color uniform piceous. Under parts greenish black, finely and 

 not densely punctured, sparsely pubescent. Legs piceous, anterior 

 tibiae and all tarsi (posterior?) paler. Length: 3.7 mm. 



Type locality. — "Texas. " Described from one specimen in the Wolcott 

 collection. Posterior tarsi massing. 



The oblique tips and color of the elytra separate this species from any 

 now known to me. 



Hydnocera pulchra, n. sp. 



Rather broad and compact, not notably convex; aeneous; antennae and 

 mouth parts piceous; knees, tibiae, tarsi and elytral maculations testaceous. 

 Head metallic greenish black, very finely and very densely punctate, ver- 

 tex finely rugose. Eyes large, convex, prominent. Pubescence moderately 

 dense, fine, depressed. Thorax broader than long (40-47) ; sides roundly 

 dilated; lateral foveae shallow but distinct; apical impressions fine, distinct; 

 surface densely rugose punctate at sides, on disk finely and densely punc- 

 tate; pubescence rather dense, depressed, pale; color greenish black, bronzed. 

 Scutellum black, moderately pubescent. Elytra considerably shorter 

 than the abdomen, toward apex dehiscent at suture, tips separately 

 rounded and nearly smooth (margin toward apex finely serrate), tumid; sur- 

 face moderately coarsely and densely punctate, punctures shallow, 

 indistinct on basal half. Surface moderately densely pubescent, the 

 pubescence as in suhfasciaia Lee, color aeneous with an irregular 

 testaceous marking on each elytron. The pale spot on the elytron is 

 almost S-shaped, commencing at scutellum, running along basal margin 

 almost to humerus, then obliquely to suture at basal third, thence along 

 suture for a short distance and finally ending at about apical fourth near 

 middle of width of elytron. Under parts aeneous, rather densely 

 pubescent, finely and densely punctate. Legs aeneous, knees, tibiae and 

 tarsi testaceous, hairy. Length: 4.8 mm. 



Type locality. — Mineral Spring, Tulare Co., Cal. 



Somewhat resembles H. hamata Lee. in coloration but differs in the finer 

 punctuation of the elytra. 



Hydnocera iowensls, n. sp. 



Form of H. longa Lee. Head, thorax and underparts brassy black, 

 elytra black with slight tinge of blue, antennae (except extreme tips), 

 trophi, anterior femora in part, anterior tibiae and tarsi pale brown. Head 

 closely and rather coarsely punctured, deeply and broadly impressed 

 between eyes. Thorax slightly broader than long (47-53), disc rough, 

 almost transversely rugose, sides coarsely and closely punctured, lateral 

 dilations broad and low, anterior and basal transverse impression deep and 

 straight. Scutellum conspicuously trapezoidal. Elytra long, suture 

 dehiscent from apical third, the apices acutely rounded and coarsely serrate, 

 punctures coarse and not crowded, evenly distributed over entire surface. 

 Vestitute sparse, erect, and evenly distributed. Under parts as in genus. 

 Basal segment of all tarsi distinctly pale, claws dark. Length: 5 mm. 



Type. — A female from Lake Okoboji, La., July 24, 1916, collected by Mr. 

 L. L. Buchanan.
