Brownsville, Tex., one specimen in the Hubbard & Schwarz 

 collection, collected by Mr. E. A. Schwarz. 



Type. No. 10443, U. S. National Museum. 



This species has the thorax more distinctly narrowing to base 

 than any other species known to me, which character, together 

 with the elytral sculpture and markings, makes it an easily rec 

 ognizable species. 



I have taken a specimen in Brownsville which is reddish 

 testaceous, with suture and side margins slightly infuscate, but 

 which does not differ otherwise; this is evidently not fully 

 colored yet. 



Bitoma pinicola, n. sp. 



Elongate, depressed, form of quadriguttatus Say, but slightly broader, 

 more depressed, the markings at best feebly defined and slightly dif 

 ferent in position. Head opaque, black, paler at apex, granulate and 

 very sparsely pubescent. Thorax broader than long, sides slightly 

 arcuate, margins feebly crenulate, disk on each side with two costae, 

 the outer distinct, the inner feeble and obliterated near apex; surface 

 granulate, piceous and scarcely pubescent. Elytra scarcely wider than 

 the thorax, disk with four slightly elevated costae, intervals with two 

 rows of coarse punctures, . which are scarcely confluent; color piceous, 

 with four not very well defined red markings on each elytron, of which 

 a narrow oblique humeral and an apical rounded spot are more visible 

 than the two others; one of them is situated near side margin between 

 the humeral and subapical spot and the other slightly below the sub- 

 apical, the latter at about apical third. Body beneath and legs piceous; 

 metasternum longitudinally strigose. 



Length, 3 mm. 



Lakehurst, N. J., on pine. 



This species resembles quadriguttatus, but is broader, more 

 depressed, the elytral sculpture not as coarse as in that species ; 

 the position of the subapical spot is different, which is in 

 quadriguttatus oblique and slightly behind middle, in pinicola, 

 when present, apparently rounded and at apical third and the 

 thoracic costse, especially the inner, are never as distinct as in 

 quadriguttatus. In the type the markings can be traced and 

 are as above described ; in a few others the markings are either 

 absent or only the humeral and subapical can be feebly seen. 



Bitoma discolor, n. sp. 



Elongate, depressed, opaque, pale rufotestaceous ; head, thorax, four 

 spots, and apex of elytra darker. Head finely granulate, sparsely 

 pubescent; antennae with ninth joint not wider than eighth. Thorax
