North Carolina, Dr. Zimmermann. The elongate oval body, and deep elytral 

 striae will distinguish this species, which seems to be variable in character. The 

 head of the male in my possession is entirely bronzed ; the thorax without any 

 distinct spots, and the elytra each with four spots, viz : one humeral, one on the 

 2d and 3d intervals before the middle, one on the same intervals behind the 

 middle, and the fourth on the 9th interval about the middle : the elytra are 

 separately prolonged into a very short point at the tip. In the female the head 

 like the rest of the upper surface is grayish testaceous, with only the occiput 

 bronzed : the thorax anteriorly has two dark discoidal spots ; the elytra besides 

 the spots above mentioned have a dark spot on the fifth and sixth intervals about 

 the middle, and their tips are prolonged conjointly into a moderately long and 

 acute spine. 



4. B. subsignatus, flavo-testaceus, ova'lia supra convexus, subopacus 

 capite confertim punctato, aeneo, postice subtiliter carinato, thorace dense at 

 haud profunde punctato, guttis duabus anticis nigris saeipe signato, elytris striis 

 profundis punctatis, interstitiis planis, irregulariter uniseriatira punctulatis, 

 macula quadrata utrinque ante medium versus suturam, lituraque communi 

 W-formi pone medium signatis, ad apicem ( % ) rotundatis vel ( <J ) brevissime 

 acuminatis. Long. -15. 



Fort G ites and Fredericksburg, Texas ; Lieut. Haldeman. The spots are ar- 

 ranged as in the second specimen of the preceding species, and the W-shaped 

 mark is formed by the confluence of the posterior ones ; the humeral dot and 

 the one on the 9th interval are 'sometimes visible, but are frequently wanting. 

 It is scarcely necessary to mention that the scutellum. as in other species, is 

 brassy. 



5. B. pantherinus, flavo-testaceus, ovalis, supra convexus nitidus, capite 

 confertim punctato, reneo, vertice leviter impresso, occipite subtiliter carinato, 

 thorace coufertim punctato, maculis anticis duabus approximatis ffineo-nigris, 

 elytris striis foriiter punctatis, interstitiis planis uniseriatim irregulariter punc- 

 tulatis, maculis plurimis nigris tesselatis, sutura nigricante, ad apicem ( ) ro- 

 tundatis. Long. -15. 



One specimen, found at Quincy, Illinois, was given me by Mr. Willcox. Re- 

 sembles in form the preceding ; the black spots of the elytra are large and about 

 10 on each, giving them almost a tesselated appearance. 



G. B. p e r e g r i n u s, ovalis, testaceus supra convexus nitidus, capite aeneo 



confertim punctato, vertice mcdice impresso, occipite obsolete carinato, thorace 



confertim punctato, lineis duabus approximatis, vel etiam disco toto iufuscato, 



. elytris striis profundis punctatis, interstitiis subseriatim punctulatis, ad apicem 



rotundatis. Long. -15.

Middle and Southern States, not rare. Varies very much in color, the spots 

 of the thorax being sometimes reduced to two small points, while at others they 

 are expanded and confluent, so as to leave only the sides and apical margin tes- 

 taceous. The elytra are spotted as in B. aculeatus, above described ; the spots 

 are, however, at times nearly obliterated. What especially distinguishes the 

 species is the deeper longitudinal impression of the vertex, which gives the ap- 

 pearance of two very flattened interocular tubercles, as described by Herbst. 

 Dr. Melsheimer's species is known to me by his kindness in furnishing me with 

 a typical specimen. 



7. B. f r a te r n u s, supra griseo-testaceus, ovalis convexus, nitidus, capite 

 aeneo thoraceque sat dense punctatis, hoc vittis duabus approximatis fuscis, ely- 

 tris fusco nebulosis, striis punctatis postice profundis, interstitiis planis disperse 

 punctulatis, 3, 5 et 7, punctis maioribus paucis notatis, ad apicem rotundatis 3 

 subtus fuscus pedibus testaceis. Long. -17.
