TOXOTUS TRIVITTATUS (Say). 



lu the early part of the present year we received into the Society's col- 

 lection, from jNIr. George Newman, a very fine % specimen of a Toxotus, 

 collected by him in the vicinity of Philadelphia. Upon examination, I 

 find that it answers to the description of Khagiuni trivittatum Say, in 

 every respect. The great difi'erence in color between this species and Tox- 

 otus (Leptura) vittlgcr Randall, which has been generally supposed to 

 be identical with it, has led me to make a careful examination of them. 

 In a large series of 30 or 35 ("J. and 9 ) specimens of vittiger^ I cannot 

 detect any variation in the coloring, which, excepting the elytral vittaj 

 and the abdomen, is black, and the 3rd joint of the antenmie is half again 

 as long as the 5th ; whereas, in trivitfatm the color is reddish-yellow, and 

 the 3rd and 5th joints of the antennfe are about equal. I, therefore, feel 

 confident that they are distinct species. 



CtAUHUTES ABDOMINALIS n. sp. 



Black ; autcunai, except first and second joints, legs and abdumen ful- 

 vous ; elyti-a bright metallic green. 



Jlab. Virginia. 



Body black, punctured, clothed with short, yellowish hairs. Head 

 very closely punctured on the vertex ; mijuth piceous. Antennte fulvous, 

 first and second joints black. Thorax black, shining, slightly punctured ; 

 suddenly contracted anteriorly and slightly posteriorly, with a dorsal sulcus 

 and an anterior and a posterior impressed band. ScutcUum black, some- 

 what conical and rouuded at tip. Elytra bright metallic green, distinctly 

 and profoundly punctured; humeri prominent; tip slightly truncate. Ab- 

 domen and legs fulvous. Length 5 lines. 



This species closely resembles G. tu/anipennis (Say), of which it may 

 possibly prove to be a variety ; but the form of the thorax and the color 

 of the abdomen and the first and second joints of the antennae, are so 

 difi'ereut, that I believe it to be a distinct species. It was collected in 

 Hampshire Co. Va., and presented to the Society by Dr. T. B. Wilson. 



Eburia? Ulkei n. sp. 

 Dark piceous; head deeply impressed in front and having two crest- 

 like elevations at the base of the antennse, separated by a dorsal stria; 

 thorax scabrous, lateral spine long and very acute; a small, round, orange- 

 colored elevation at the base of each elytron between the humerus and 

 scutellum.
