by its shorter and more robust form and system of coloration. The 

 differences will be made known under that species. 



This species appears to have been widely distributed over the entire 

 globe and has several times been described under other names. The 

 foreign synonymy has been omitted as not pertinent to the present 



B. quadrimaculal US, Fab. Syst. El. ii., p. 398 ; Ent. Syst. i., ii., p. 371 ; 

 Oliv. Ent. iv.,p. 49, pi. 3. fig. 24. — Elongate oval, moderately shining. Beneath 

 equally clothed with whitish pubescence. Elytra ferruginous or pale brown 

 with large lateral spot and apex broadly black. Head dark brown or black, 

 densely punctured, front sub-carinate. Antennae as long as head and thorax, 

 serrate in both sexes, four basal joints pale rufous, outer joints dark and nearly 

 black. Thorax trapezoidal, broader at base than long, sides distinctly arcuate, 

 base trisinuate, basal lobe emarginate and clothed with whitish hairs; color 

 variable from ferruginous to black, coarsely punctured, sub-granulate and fee- 

 bly shining, sparsely clothed with cinereous hair. Scutellum with median 

 impressed line and clothed with whitish hair. Elytra broader at base than 

 thorax and longer than wide, sides feebly arcuate, humeri moderately promi- 

 nent; striate, striae punctured, intervals flat densely punctulate; color ferru- 

 ginous with large lateral spot and apex black, clothed with whitish and cin- 

 ereous pubescence. Pygidium nearly black with median line of whitish 

 pubescence. Body beneath piceous densely punctulate and sparsely but 

 evenly clothed with cinereous hairs; abdomen pale brown. Anterior and mid- 

 dle legs pale rufous, hind legs pale brown. Hind femora armed with an acute 

 tooth on the inner side aud a broad triangular tooth on the outer side. Length 

 .12— .18 inch; 3—4.5 mm. 



The great majority of specimens are nearly black with the elytra 

 pale brown with the four spots as indicated. An occasional specimen 

 is seen of rufous color as figured by Olivier, which has the elytra in 

 great part deprived of pubescence. The pubescence is cinereous but 

 with the third interval with a short white line, at each end of which is 

 a brownish spot; between the external and apical spots an irregular 

 whitish band. The lateral spot has at times a patch of pubescence at 

 its centre so that the color of the spot is concealed and it then appears 

 as a sinuous band. 



B. quadrimaculatus is closely allied to Scutellaria, but differs in 

 many points. The thorax is broader, the sides distinctly arcuate, the 

 basal lobe not eburneous. The scutellum is flat and with median line. 

 The elytra are longer, and differently spotted and the abdomen is 

 evenly clothed with cinereous pubescence. This species is also larger 

 and much less robust. 



Occurs in the West India Islands and the Southern States.
