Mr. F. Smith on Hymenopterous Insects captured in India. 45 



I am only acquainted with one other species belonging to this 

 genus ; it is from South America, and is in the National Collec- 

 tion at the British Museum. I subjoin a description of the in- 

 sect in a note *. 



Genu3 Hedychrum. 



Hedychrum rugosa, n. s. 



Length 3 lines. Head, and thorax golden green, rugose -punc- 

 tate ; the eyes, antennae and tegulse black, the scape of the 

 antennas tinged with green j the tarsi rufo-piceous, the punctures 

 on the scutellum and metathorax very large. The abdomen is 

 green with a blue reflection, much more finely punctured than 

 the thorax, except the sides of the basal segment which are rugose. 



Hab. Poona. 



Genus Chrysis. 



Chrysis pubescens, n. s. 



Length 3| lines. Head and thorax brassy-green, rugose-punc- 

 tate ; the eyes and antennas black, except the basal joint, which 

 is brassy-green; the anterior margin of the prothorax deeply 

 incurved, receiving the vertex of the head, the metathorax pro- 

 duced laterally into obtuse spines ; the tegulae and legs brassy- 

 green, the tarsi rufo-testaceous ; the wings dark fuscous, some- 

 what paler at their apical margins. Abdomen green, with a blue 

 reflection, the apical segment chalybeous, quadridentate ; the 

 whole abdomen deeply punctured, and having, as well as the 

 head and thorax, a short thin pubescence. 



Hab. Bombay. 



This species is parasitic on Pelopams; the following are Capt. 

 Downes's remarks : " A nest of Pelopmis was taken on the wall 

 of my room ; several of the cells were broken down whilst re- 

 moving them, and various sorts of spiders fell out ; one of the 

 cells was a little denuded of its mud, so that I could see inside ; 

 this hole was repaired next day by a thin substance like talc, and 



* Tetraponera testacea. 



Female (length Z\ lines) testaceous, smooth and shining ; the head elon- 

 gate, truncate in front and behind, slightly emarginate at the vertex, a 

 shallow impressed line running from the anterior stemma to the base of the 

 antennae, where it terminates in a deep sulcation carinate on its sides ; the 

 eyes black, the mandibles ferruginous, roughly channelled longitudinally 

 with irregular striations, the teeth black ; the mesothorax is darker than 

 the rest of the thorax, and has a longitudinal scratch on each side ; the 

 metathorax is rounded posteriorly, very smooth and shining ; the abdomen 

 has a few scattered long hairs at its apex, and also on both its nodes ; the 

 third segment is also slightly constricted. 



Hab. Napo, S. America.
