— Tempora distinctly margined almost up to the verlcs. Body (oxoept in one 



variety) partly red 5. 



5. Hind-wings without enclosed medial cell. Abdomen black. 



(«) Thorax mostly red diiliiis, Gm. (typical form). 



(= ephipphim, C). 



(i) Thorax black dubins, Grm., var. nigrans, Knw. 



(? ^ hrachycera, C, Vol. IV). 



— Ilind-vviiif;s wilh enclosed medial cell. Abdomen and legs for the most part red, 



thorax black. (A larger species than the last ) luteiventris, Kl. 



{^=fttscipe)mis, C). 



I liave already reonrdod Britisli ('aj)tiires of T. funereus and 

 T. ga(jniliinns in tlio Ent. Mo. Ma;^. (Jan., 1901). The former 

 I received from tlie late Mr. Beaumont, the latter from the Rev. A. 

 Thornley. The variety of dubins with black thorax (^nigrans, Knw.) 

 has been sent to me by several correspondents, ainon<; them Mr. li. C. L. 

 Perkins, and T have also examples taken by Dr. Capron. I notice that 

 in all my specimens of this form, and likewise in those of the typical 

 ihihhis, the horny spot which is usual, if not universal, in the 2nd 

 cubital cell of other Tomostethus s[)ecies is wanting ; and as Mr. 

 Cameron characterizes a Tomostethus which lie formerly called micans, 

 but now hraclnjcera, by the absence of this spot, it occurs to me that 

 hracliycera^ C, and var. nigrans, Knw., may j)erliaps be identical. 

 But as I have not seen the type of hrachycera, and do not know 

 ■whether the presence or absence of such a spot can really be relied 

 iijion as a good specific character, I only Ihi'ow this out as a sug- 

 gestion. 



Blennocampa, Jltg. 



Next to Tomostethus in his Catalogue Konow places the genus to 

 which he restricts the name of Blennocampa — a name applied by 

 previous authors to the whole of (he present group. This genus, as 

 he now defines it, consists of those; Blennocampides whicli combine 

 the following characters : short cheeks, no distinct pra?sterna, 3rd 

 antcnnal joint longer than Ith, 1st cubital nerve in fore-w^ing distinct, 

 discoidal n. and 1st basal n. sub-paralli'I, and no enclosed medial cell 

 in the hind-wing, Of Blennocampa as thus defined, 1 know six 

 British species, which ajipear to be all common insects, and which can 

 be separated from one another without much difficulty as follows : —
