with one enclosed medial ci'll. Tlic species are of medium size 

 (about 5 — () mill, long.), and the only three known to mo for certain 

 as British are all black-bodied insects. The most common of these is 

 probably albipes, but none of them are rare. 



SYNOPTIC TABLE OF BRITISH MONOPHADNUS spp. 



1. Fourth joint of antennae about lialf as long as the third. Radial n. in fort'- 



wing remote from 3rd cubital n. (Legs wiiite and black, with black hind 

 femora) aliipes, Guiel. 



— Fourth joint of ant. quite two-thirds of the length of the third. Radial n. in 



fore-wing nearly or quite interstitial 2. 



2. Pronotum, tegubr, and at least the greater part uf the hind tibiae black... 



genicuhdus, Illg. 



— Pronotum, teguhe, and hind tibifc yellowish rujicruris, Bridle. 



These speciea are all described under the same names by Mr. 

 Cameron. The genicuhitus of Htg. {B. qeniculata, C.) is not to be 

 confounded with (/eniculata, Steph. 'I'he latter is Mr Cameron's 

 B. aJternipen, and is not a Monophndnus, but a true Blennocampa.

PSEUDODINEUKA, Kuw. 



This genus was established by Konow in 1S85 for the reception 

 of certain species previously classed as Nematids, but excluded from 

 that group as he defines it, by their short cheeks, and by the imperfect 

 development of a "humerus "in the hind-wing. The only British 

 species known to me is/uscula, Kl., of which I have specimens from 

 Dr. Capron's collection determined for me by Konow, but there are 

 probably others belonging to it among the species referred by Mr. 

 Cameron to Dineura. The latter author's Dineura despecta is, perhaps, 

 but according to Konow, "not certainly," identical w\th fuscula : it 

 seems not to be the despecta of Htg., which belongs to Konow's 

 genus Mesoneura. 



Kaliosyspiiinga, Tischb. 



The species referred by Konow to this genus form a part of tho.-<e 

 included by Cameron in Fenusa. I possess British specimens of 

 three species, viz. : ulmi, Sundev., duhrni, Tischb., and me/anopoda, 

 Cam. (= nigricans, Thoms.), but will defer their tabulation till the 

 end of the {)resent paper. The generic characters of KdJiosysphinga 

 have been given already — it differs from Fenusa {sec. Knw.) in two 

 points of neuration, in the fore-wing the humeral area has a decep- 

 tive appearance of being " contracted," and in the hind-wing the 

 " humerus " (as in Pseudodineura) is imperfectly developed or even 

 entirely wanting. 



Fenusa, Leach.
