PARAB.VTUS. — TETRAGOXALYS.

Kokiijew in his ' llyinenopteni Asiatica Nova,' Avlieu Cameron 

 described it as new from Assam. I have no hesitation in 

 synonj-mising his name, since the description he gives differs in no 

 way from that of P. virgatus, auctt. It has frequently been bred, 

 always from Lepidoptera, and its hosts comprise many kinds of 

 Jjombycicls,Noctuids, and Greoraetrids (c/'. Bridgman & Fitch, I.e.). 

 The Oriental specimens diifer in no way from those taken in 

 Britain.

c^ $ . A somewhat stout, red species, with the wings flavescent 



and very ample, the thorax 

 entirely subinfuscate and 

 the second recurrent ner- 

 vure straight. 



Length 15-19 millim.

Type in the British 



Museum. 



Too closely allied to the 

 preceding species to de- 

 mand a detailed descrip- 

 tion, but at once recognised 

 therefrom by its larger size 

 and wings, which are strongly flavescent and peculiarly ample, 

 with the recurrent nervure hardly at all curved, the upper basal 

 much less curved and the lower basal emitted very slightly befox'e, 

 in place of very slightly beyond, the upper, as is the case in 

 P.virgatus; the metathorax is more deplanate and the nervellus 

 intercepted in its centre. Similar to P. gaiisuaniis, Kok., from 

 China, but with the metathoracic costse strong, and the stigma red 

 and of normal breadth.

Head strongly constricted behind the internally parallel and 

 (next the scrobes) strongly emarginate eyes, which are liardly 

 broader than the thorax ; clypeus subconvex, discrete basally, and 

 upically margined and very broadly rounded ; mandibles stout, 

 with the apical teeth of equal length ; palpal joints elongate and 

 cylindrical ; frons strongly deplanate below the prominent ocelli, 

 which are laterally contiguous to the eyes ; vertex very narrow 

 and basally bordered throughout. Antenna; as long as the body, 

 filiform and apioally subattenuate. Thorax not very stout, sub-
