? . Posterior lobe of the prothorax deeply divided by an 

 oval excision ; rhinarium and upper lip blackish ; inner border 

 of the eyes and the cheeks yellowish. (The last three segments 

 of the abdomen are missing.) 



This species is allied to 7\ Dictynna, but very distinct by 

 the two pale spots of the front of the thorax being very much 

 smaller, the lateral bands more dilated, and the pterostigma 

 longer. The ? is remarkable for the oval excision which di- 

 vides the posterior lobe of the prothorax. The appendices of 

 the c? are formed like those of T. cyanops ; only the superior 

 are rather more excavated internally, and the inferior rather 

 less contiguous before the apex. 



Until the present time the genus Trichocnemis was known 

 only from South Asia and the Malayan archipelago. 



8. Agrion senegalense^ Rambur. 



Two males similar to those of the African continent and 

 islands. 



9. Brachyhasis glabra j Burm. [Agrion). 

 Agrimi ferrugineum, Rambur. 

 Two males, similar to those of the African continent, Mada- 

 gascar, and Mauritius.

The three following appear to be degraded Tasmanian forms 

 of Cestrinus, Er.*, and are closely allied ; they are narrower 

 and more feebly constructed, and the prothorax wants the ex- 

 panded margin. Opatrum piceifarse, Hope, belongs to this 

 genus ; with this species his Isopteron opatroides exactly 

 agrees, only the latter has clear ferniginous antennae. The 

 same author's Platyiiotus insidaris is, I believe, another mem- 

 ber of the genus. The descriptions of these insects and some 

 others, in the ' Transactions of the Entomological Society ' 

 (scr. 1. vol. iv.), were very concise; and they were left un-
