$ Black or piceous ; 1st abdominal segment flavo-ferruginous. 

 Oral parts and palpi of the same colour. Antennae 14- (or sometimes 

 15-) jointed, black, with the base yellow. Prothorax flavo-ferruginous. 

 Wings hyaline ; squamulse and radicles stramineous ; stigma almost 

 hyaline ; nervures for the most part colourless ; cubital nervure 

 colourless, scarcely perceptible beneath the 1st cubital areolet. Legs 

 flavo-ferruginous. Haliday had before him some specimens, probably 

 immature, in which the black parts were replaced by brownish red, 

 and the scutellum was red ; but he regarded them as belonging to 

 the same species. $ Unknown. Length, | ; exp. U lines. 



This species was doubtfully referred in the Catalogue of 

 1872 to matricari£e and resfrictus (sp. 28) ; but such a 

 conjecture should not perhaps have been made without 

 more information. The insect has never been bred by any 

 one, and its description leads to no certain conclusion. 



Found by Haliday upon reeds, but not common.

? Head and thorax black ; abdomen subsessile, brown, with the 

 1st segment and the base of the 2nd whitish yellow. Clypeus, 

 mandibles, and palpi very pale, somewhat rufescent. Antennse 12- 

 jointed, rather larger than the head and thorax, stout, submoniliform, 

 black, with the two or three basal joints pale rufous, the apical 

 joint elongate and larger than the rest. Prothorax often testaceous 

 beneath ; mesonotum without furrows ; metathorax rufescent, smooth, 

 without a median carina, and not areated. Wings hyaline ; squa- 

 mulse, radicles, stigma, and nervures pale brownish, these last 

 tolerably distinct, except the cubital, which is efl'aced as to its first 

 section, reappearing only to form the lower side of the 1st cubital 

 areolet. Fore legs testaceous ; the 4 posterior brownish, with coxse, 

 trochanters, and knees, pale testaceous. Abdomen rather longer 

 than the head and thorax, lanceolate, slightly compressed at the apex ; 

 1st segment short, not more than twice as long as its mean breadth, 

 linear as far as the tubercles, which are situated before the middle, 

 from thence widened to the extremity, which is twice as broad as 

 the base ; posterior segments gradually becoming darker to the apex 

 which is nearly black. Valves of the terebra black. ^ Similar;
