170 LENG AND HAMILTON. 



Oxopliis cocciitens Casey, 1893, An. N. Y. Acad. Sci. vii. 588. 

 Lensrth 19-20 ram. = .75-. 80 inch. Hnhitat. — ^Utah (soiith western). 



Described from three males as bright scarlet except the head, an- 

 teniise, entire uiuler surface between the front and hind coxjis, apical 

 and basal bead of the thorax, scutellum, ba.sal margin of the elytra 

 and a common sutural dash in apical half, black ; this dash in the 

 female becomes very broad, extending to the middle, but not attain- 

 ing the margin, except near tip. 



This may be placed in the table next corallinns, examples of which, 

 in my collection, are uncomfortably close to it as described. 



CrossixliiiN blaiidi Casey, 1893. An. N. Y. Acad. Sci. vii, 589. 

 Length 7.7-9.5 mm. = .30-.38 inch. Hohitat. — Southwestern Utah. 



This species may follow^ discoideus, to which it is closely allied in 

 the table heretofore given. It is represented as differing from dis- 

 coideus in its smaller size, narrower form, s})arse punctuation, espe- 

 cially the thoracic, the absence of the two subapical black spots on 

 the thorax, and the rounded and not truncate apices of the elytra. 



The following species belong to the group of Cfossidius with the 

 thorax subtuberculate : 



Crossiilius loiigipeiiiiiK Casey. 1891, An. N. Y. Acad. Sci. vi, 31. 

 Length 15-19 mm. = .60.75 inch. Habitat. — New Mexico. 



Described from four examples, and stated to be related to inter- 

 mediiis but larger, differing also by the punctuation finer and denser, 

 the black legs and antennae, and the truncate and angulate elytral 

 apices. 



CrossidiiiK crassipes Casey, 1891. I. c. p. 32. 

 Length 14 mm. = .56 inch. Habitat. — Washington. 



Described from a single male example as intermediate between 

 pundatiis and intermedium, having the black legs and antennae of 

 the former and the long slender antennae of the latter, and differing 

 from intermedim in the very long posterior tarsi, in which the second 

 joint is nearly one-half longer than wide. 



Crossidius iiitidicoIli>« Casey, 1891. An. N. Y. Acad. Sci. vi, 33. 

 Length 10.5-12.5 mm. .= .50-.60 inch. Habitat. — Arizona (Tucson). 



Descril)ed as allied to jyidcheUiis, but differing in the larger and 

 longer thorax, with the extremely slender and acute lateral prolon- 

 gation of the basal angles more conspicuous ; and by the characters 

 in the synoptic table of the species in the group with rounded and 

 semituberculate sides which is here reproduced.
