Pentaria lufeicoUis, n. sp. 



Very like F. ktimaonensis : finely sericeo-pubescent, black, the antennae 

 (the infuscate joints 7-11 excepted), palpi, prothorax, and legs testaceous ; the 

 sculpture of the upper surface extremely tine. ^ . Anterior femora very stout, 

 angulate towards the base beneath, and hollowed thence to the apex ; anterior 

 tibiae (fig-. 3) sharply triangularly dilated near the base and also widening- again 

 at the apex within. 



Length (excl. head) 2-2^ mm. 



Hah. Ranikliet, Almora District (H. G. C. : v.1920). 



One (5,3 5 ?• Separable at once from the three other Indian 

 Pentariae named by myself by the black head and elytra, the testaceous 

 ])rothorax and legs, and the form of the 6 anterior femora and tibiae, 

 the insect coming nearest to P. chloyoptem in tlie tibial structure.

A NEW GENUS AND SPECIES OF ORTHOPTEKA FOUND IN A 

 GREENHOUSE IN ENGLAND. 



]!Y B. P. UVAROV, F.E.S. 



Dr. L. Chopard, during his recent visit to London, when looking 

 through the collection of English Orthoptera in the British Museum, 

 drew my attention to a couple of specimens (one immature) of wingless, 

 spider-like, long-horned grasshoppers which have been erroneously in- 

 corporated amongst the series of the common greenhouse grasshopper, 

 Tachycines asynamorus Adel. After a short examination of these two 

 insects, he proclaimed them to belong to an undescribed genus related to 

 DoUchopoda, and he left its description most generously to me, though 

 he himself is undoubtedly the best living authority on this particular 

 group. My detailed study of the species conlirmed Dr. Chopard's 

 opinion that it belongs to the group " Dolichopodini," and I am very 

 pleased to name the genus after Dr. L. Chopard. 

 The description of the insect is as follows : —

Belonging to the group Dolichopodini and closely related to Gijmnoplcctron 

 Hutton, bul diil'ering from it in the armature of the legs. 



Antennae setaceous, not less than four times as lung as the body 

 moderately separated at the b .ses ; hrst joint somewhat imrMssate, about 

 twice as long as thick ; second joint much narrower, slightly longer than 

 broad ; the following joints short, bearing- small scattered hairs ; antenual 

 scrobes with the inner margins raised and separated by an interspace sidjeqnal 

 in width to the third joint of the antennae. Head vertical; occiput feeldy 

 convex; vertex sloping, not vertical, its fastigium in the shape of a rather
