AMERICAN COLEOPTERA. 93 



acute at its apical end. With the known variation of the preceding; 

 .species I am unwilling to separate this as distinct but prefer to con- 

 sider it nearly a variety under the name of hiimera/is. Both males 

 and females are before me, the anterior tarsi of the male as distinctly 

 dilated as in the preceding species. The typical specimens in the 

 ca'tinet of Dr. Leconte are females, hence the failure to mention this 

 very obvious character. In the male the front is rather deeply sulcate 

 but the lateral tubercle is less evident than ia the male of i^crpnl- 

 chra. 



C. mirabilis, n. sp. — Palo rufous, elytra pale yellowish. Head broadly oval, 

 gibbous between the bases of the antennse, sparsely puncture>l. Thorax oval, 

 as broad as long, strongly narrowed in front, and slightly narrower at base ; 

 median and ba-sal impressions moderately deep. Elytra oblong, broader be- 

 hind, humeri moderately prominent, margin reflexed, suture elevated, and 

 with four strongly elevated eostre on the disc of each elytron, extending from 

 base nearly to apex. Color pale yellow, with four small brown spots at base, 

 arranged in arc with convexity backwards, an iriogular narrow transverse 

 band at middle interrupted by the costoe, and a narrower sub-apical band. 

 Body beneath and legs, pale rufous, abdomen paler and more shining. Length 

 .46 inch ; 11.5 mm. 



The entire surface of body is very sparsely clothed with very short 

 silvery white hairs, longer on the legs. The intervals between the 

 elytral cost39 are nearly flat and sparsely punctured. The small 

 brown spots at base are arranged between the suture and first ccsta, 

 and between the first and second. The tarsal claws are divided, the 

 upper and lower portions being connate, and the latter shorter. The 

 antenna; are as in the other species of Caloapanta. With one excep- 

 tion (^Pieuropompha costata, Lee), this is the only Meloide in our 

 fauna with costate elytra. 



The specimen in my cabinet is from Southern Arizona, and was 

 obtained through the Agricultural Bureau at Washington. 

 Tegrodera erosa, Lee. Ann. Lye. V, 159. 



Two varieties of the species occur. Specimens collected by 3Ir. 

 Gabb in Lower California have the elytra very coarsely reticulate and 

 the transverse black band entirely wanting. Those collected by my- 

 self in Owen's Valley have the elytra more finely reticulate and a 

 broad median and apical black band. Specimens from San Diego are 

 nearly intermediate in sculpture and color. I am unable to detect any 

 differences of a specific nature. The male has the last segment of ab- 

 domen slightly eujarginate. 



Zonitis longicornis, n. sp. — Elongate, pale brownish testaceous; opaque; 

 margin, suture and narrow stripe extending from humerus to tip paler. Ileail 

 nearly black, verte.x paler very densely and coarsely punctured, rugose.
