Fi'ont black. Thoi'ax strongly curved, black or dark-brown, 

 rather sparsely covered with short black hairs, which are 

 longer on the margins. Scutellum black, with a row of hairs 

 on its posterior margin. Pleurae and metathorax black. 

 Abdomen black, but third and fourth segments dark-brown, 

 sparsely covered with short black hairs. Legs rather short; 

 coxae smoky ; femora compressed, yellow in the centre, but 

 bordered with dark-brown ; tibise rather longer than the fe- 

 mora, not slender, the two posterior pairs with a few mode- 

 rately - long black spines, anterior tibiae without spines ; 

 spurs rather stout, straw-coloured, and covered with a light 

 pubescence. Wings brown, darker near the costa and in the 

 central portion of the first submarginal cell. Inner marginal 

 cell long, its apex being nearly directly above the apex of fork 

 of third longitudinal vein ; cross-vein situated near the end 

 of first longitudinal vein ; costal vein ending before the tip of 

 the wing ; second longitudinal vein joining it some distance 

 before its tip. Surface of the wing microscopically pubescent. 

 I have only one specimen, taken at Lincoln College, in 

 September. 



Genus Eurycekas, gen. nov. 



Head oval, not very deeply imbedded in the thorax. 

 Eyes large, round, slightly emarginate on the inner side 

 above. Palpi incurved, rather short ; first and second joints 

 about equal, short ; third joint about double their length, 

 cylindrical ; fourth joint still longer, slightly clavate. Ocelli 

 three, large, placed almost in a straight line on the broad 

 front. x\ntenn£e 2 + 14 jointed, about as long as the head 

 and thorax together ; joints of scapus much broader than 

 long, cupuliform, setiferous above ; fiagellum compressed, 

 broadest part in the middle, joints generally broader than 

 long except at the apex, densely pubescent. Thorax highly 

 arched, pubescent, without strong setae on the lateral margins. 

 Scutellum rather small, semicircular, hardly setiferous. Me- 

 tathorax steep. Abdomen rather flattened, seven-segmented, 

 narrow in front but broader posteriorly. Forceps of the male 

 rather small, chelate. Legs rather slender ; coxae short but 

 stout, hairy ; femora slender, but posterior pair compressed, 

 pubescent ; fore tibiae larger than the metatarsus but less 

 than half the length of the whole tarsus, intermediate tibige 

 rather shorter and posterior tibiae longer than the tarsus, 

 three ranges of small spines on fore and intermediate tibiae 

 and two ranges of longer spines on posterior tibiae ; spurs 

 rather short ; first not much longer than second joint of 

 tarsus, a few small prickles on the under-side of tarsus. 

 Wings rather pointed at the apex, and anal angle rather 

 prominent ; surface of wings distinctly hairy. Auxiliary vein
