78 NEMATUS LATIVENT1US. 



dividing the scutellum as it were in two. This species 

 cannot certainly be pallipes, Thorns., for that has the 

 antennas as long as thorax and abdomen, the pronotum 

 is almost entirely pale, the cerci short, the abdomen is 

 " almost cylindrical," while in carinatus it is broad and 

 flat, broader in the middle than the thorax, ending in 

 a blunt point at the apex, the testaceous colour on 

 apex too being much less. Besides these differences 

 pallipes has the legs, including coxa3, almost entirely 

 testaceous. 



It agrees tolerably well with the description of cari- 

 natus, of which the $ only has been described by 

 Hartig, but the ? , according to Zaddach (Schr. Ges. 

 Konig., xxiv, p. 129), has the legs fulvous, the antennas 

 longer and more slender than in mollis, which is cer- 

 tainly not the case with the present species ; the edge 

 of the pronotum is fulvous. Zaddach gives N. aqui- 

 ligece, Vol., as a synonym of carinatus, and he also 

 quotes pallipes, Thorns. (? Fall.), as a synonym. 



21. NEMATUS LATIVENTEIS. 

 PL XVII, fig. 4, Saw. 



Nematus lativentris, Thorns., Hymen. Scand., i, 99, 23 ; Andre, 



Species, i, 145, 41 (excl. syn.). 



Black, short, thick ; antennae as long as the abdomen ; mandibles 

 piceous. Legs black, the apical third of anterior femora, the knees of 

 posterior, the tibiae and tarsi, dirty testaceous ; anterior tarsi marked 

 with fuscous ; apex of posterior tibiae and tarsi black ; spurs one-third 

 of the length of metatarsus. Tegulae piceous-yellow ; edge of pro- 

 notum dirty testaceous. Wings hyaline, costa and stigma yellowish- 

 white. Abdomen short and thick, apex of last segment dirty brown ; 

 cerci long, sheath hairy, projecting. 



Length 2f lines. 



Distinguished from N. astutus by its short, oblong 

 Selandria-like body, which is shorter than the wings ; 

 black labrum, no ridge on scutellum, and the furrow 

 on middle lobe of mesonotum is scarcely distinguish- 

 able ; the spurs are shorter and metatarsus longer. The 

 testaceous colour on the pronotum is better marked
