the name of one of which, pallidas, conflicts with Corizus pal- 

 lidas J. Sahlbg. from Siberia. I am rather inclined to agree 

 with Mr. Baker in his determination of nigristernum and Bo- 

 hcmani He places the former name on the dark form of 

 lateralis and the latter on the species usually determined in this 

 country as nigristernum:. I doubt very much if the identity of 

 some of the species of Signoretand Dallas can finally be determ- 

 ined without reference to the types. 



58. Jadera haematoloma H. S. 



Sanford; one example. 



Family Metacanthidae. 



59. Jalysus spinosus Say. 



This species was not at all abundant. I took it at Crescent 

 City and Clearwater only. About Buffalo it is very rare but 

 from New Jersey to Colorado it is the predominant form. 



60. Jalysus perclavatus n. sp. 



Allied to spinosus and Wickhami but much smaller and 

 with a thicker and shorter antennal knob. Color pale testa- 

 ceous yellow as in the allied species. Disk of the pronotum 

 and clavate apex of the femora a little darker; apical joint of 

 the antennas, tarsi and apex of the rostrum black, the former 

 polished and clothed with scattering minute hairs; abdomen 

 more testaceous, sometimes tinged with greenish and darkened 

 to olive on the venter. Head about as long as the posterior 

 lobe of the pronotum ; vertex elevated anteriorly and produced 

 in a rather long, almost erect blunt spine between the bases of 

 the antennae. Antennas: first joint but little shorter than the 

 two preceding together, clavate at apex; second nearly as long 

 as the third; fourth unusually short and thick, fusiform, a 

 little shorter than the head and almost half as thick. Rostrum 

 attaining the intermediate coxae, first joint just reaching the 

 base of the head. Scutellar and metapleural spines tinusually 

 long. Hind femora surpassing the abdomen by the length of 

 its clavate apex in the male, but very little exceeding the ab- 

 dominal tip in the female. Elytra almost hyaline, the tip of
