genera and species of Buprestidce. 



179 



scutello cyaneo, nitido ; elytrig seneis, fortiter striatis, plaga scu- 

 tellari, altera ad medium (ad suturam non attingenti) brunneo- 

 seneis nitidis. Long. 10£ mm. 



The head is closely and moderately strongly punctured. The 

 thorax is rather more strongly punctured ; 

 the three basal impressions extend nearly 

 to the middle, the central one is rather 

 wider than the others ; they are slightly 

 tinted with bluish green at the base. The 

 suture of the elytra is green ; the interstices 

 are slightly costiform, except below the 

 shoulder and near the suture in the middle. 

 There is a quadrangular patch occupying 4 

 the scutellar region, and a second square 

 spot about the middle of a more brown 

 colour, more shining, and slightly more 

 raised than the rest of the elytra ; the 

 humeral callosity and the margin near the 

 base are also of the same bronzy-brown 

 colour ; the margins near the apex are finely denticidate. The 

 sterna, abdomen, and legs are bluish green, varied with blue, 

 purple, and aeneous.

Trypantius, n. g. 



I propose this name for Stenogaster bitceniatus, Chev., 

 and an allied species. The chief character of Steno- 

 gaster is the somewhat remarkable fact that only the 

 4th joint of the tarsi is furnished with a lamina ; it is 

 therefore quite inadmissible that S. bitceniahis, which 

 has the 2nd and 3rd joints also furnished with a short 

 lamina, should be included in the genus. The costa of 

 the elytra does not reach the base, which is the case 

 in Stenogaster; the forehead has a deep longitudinal 

 furrow, and the channel on the inner margin of the eye 

 is also very deep. 



Trypantius infrequens, n. s. 



Elongatus, angustus, depressus, seneus, nitidus, crebre punc- 

 tatus, parce griseo-pubescens, pube ante apicem elytrorum in 

 fasciis duabus congesta. Long. 10 mm. 



Very similar in form to T. bitcsniatus, but narrower and more 

 regularly narrowed posteriorly. Head moderately strongly and
