Head and thorax as in the preceding species, the thorax with two 

 short fuscous patches. Elytra pale testaceous, deeply striate, outer striae 

 deeper, striae coarsely punctured, intervals flat, finely alutaceous, irregu- 

 larly punctured, punctures not deeply impressed. Body beneath and 

 legs, pale rufo-testaceous. Mesosternal crest moderate, mucronate at

Head as in aculeatus, thorax less densely punctured, sides apparently 

 convergent in front, disc bimaculate. Elytra less deeply striate than 

 either of the two preceding species, stria; coarsely punctured, intervals 

 roughly punctured ; color pale yellowish testaceous, sutural interval fre- 

 quently piceous, on each elytron ten black spots of moderate size, one 

 humeral, another within and slightly below it, four arranged in a sinuous 

 transverse band in front of middle, three arranged transversely behind 

 the four and one sub-apical. Body beneath pale rufous, abdomen usually 

 darker. Legs pale testaceous. Length .16 inch ; 4 mm.

Resembles the preceding species in form and color, and differs as 

 follows. Head slightly impressed between the eyes, vertex finely sub- 

 carinate. Elytra yellowish testaceous, stripe of the disc less distinct

 indistinctly defined. Body beneath variable in color from pale rufo-tes- 

 taceous to piceous without reference to sex. Sexual characters as in 

 panthennus. Length .16 inch ; 4 mm. 



Occurs from Massachusetts to Missouri, Florida and Arizona. 



B. immaculatus, Zimm. Trans. Ent. Soc. 1869, p. 249. 



Smaller and more slender than the preceding, and totally yellowish 

 testaceous with but slight traces of spots on the elytra. The elytra are 

 more deeply striate and comparatively more coarsely punctured, the 

 intervals convex and approaching pantherinus in rugulosity. Sexual
