June, 1918.] NiCOLAY & WeiSS : BUPRESTIS IN NORTII AMERICA. 85 



This species appears to be both local and rare. Few of our eastern 

 collections have it represented by more than one or two examples. 

 The two forms (intricata and brevis) described by Casey have no 

 good constant characters and should be placed in synonymy. 



Buprestis sulcicollis (Le Conte), 59-20S. 



lateralis Casey, 09-119. 



Convex. Elytra obliquely narrowed and slightly prolonged at apex, uni- 

 form, dull, dark, coppery brown usually with a very slight tinge of green, 

 four elytra! costse, suture and margin elevated, third of true elytral costae 

 very short. Antennae dark, first two segments bronzed. Head and pronotum 

 dark coppery brown, latter deeply channeled, pronotum becoming arcuate 

 toward base. \'entral surface dull cupreous, densely punctate, punctures of 

 presternum coarse, those of abdomen fine, tip broadly rounded. Length 

 1 3-1 5.5 mm. 



Records. — Lake Superior (Le Conte). Monmouth, June 24; 

 Paris (Frost) ; Maine. Hampton (Shore) ; New Hampshire. 

 Marquette, June 25 in wash up (Sherman); Michigan. Keene 

 Valley, Essex County, July (Notman) ; New York. Nova Scotia. 



Food plants, white and pitch pine. 



This species is exceedingly rare and appears to be confined to the 

 northeast. The occasional records from Florida and the south un- 

 doubtedly refer to the true Buprestis striata which is also a uniform 

 dark coppery brown above, but which is easily separated by the char- 

 acters given in the key and also by the pronotum not being channeled 

 as it is in sulcicollis. Dr. E. C. VanDyke who examined the type in 

 the Le Conte collection finds that it is not a brassy green insect as 

 claimed by Casey but of a uniform dull, coppery brown with a very 

 slight greenish reflection. This places the dark form described by 

 Casey as lateralis in synonymy. 



Buprestis striata (Fab.), 75-267. 



obscura Casey, 09-125. 



Elongate. Elytra dark coppery brown with a cupreous shine, four elytral 

 costae, suture and margin elevated, costas flat and punctured, intervals densely, 

 coarsely and confluently punctate. Antennas greenish, more or less bronzed. 

 Head and pronotum uniform dark coppery brown with a cupreous or brassy 

 luster. Head and pronotum densely and coarsely punctate, sides usually 

 parallel, slightly sinuate, rarely arcuate or broadened posteriorly. Ventral 

 surface and legs bronzed or cupreous. Prostermnn densely and coarsely, ab- 

 domen, finely punctate. Male narrower than female with tips of abdomen 

 more broadly rounded. Length 13-20 mm.
