him. This summer, had he lived, my debt would have been largely 

 increased ; for we had planned that I should visit him bringing my 

 entire "British "material" of certain troublesome genera (Dolerus, 

 Tenthredopsis, &c.) for final study and comparison with his own 

 collections, before I came to write upon them. It is with no little 

 anxiety that I now face the prospect of having to continue this work 

 without the help that has hitherto made it comparatively easy, and 

 on which T had counter! as available till my task should be completed. 

 Proceeding now in our consideration of the British Selandriads 

 we come to the genus from which the tribe is named, viz., Selandria, 

 King. ; and along with this I propose in the present paper to treat 

 of three other genera, formerly united under the name Sfrongylogaster, 

 Dahlbom, but distinguished by Konow in 1885 as Sfrongylogaster, 

 Thrinacc, and Stromboceros. All species of Selandria and nearly all 

 of the other three genera* possess the verv unusual and easily 

 recognised character of a perfectly simple "open lanceolate cell" 

 (Ent. Mo. Mag., 1903, p. 51, fig. 4,a). An insect having that 

 neuration, along with a broad ovate abdomen, and a costa conspicuously 

 thickened before the stigma, may be set down at once as a Selandria ; 

 but if the abdomen be elongate and cylindrical, and the costa simple, 

 it should be sought in the three other genera. 



Selandria, Klug. 



Selandria embraces a fairly large number of "British species — all 

 very uniform in general habit, but divisible by colour into two w r ell- 

 marked groups, in one of which the abdomen is red or orange (testa- 

 ceous), while in the other it is entirely or nearly entirely black. The 

 first group have a superficial likeness to Athalia-syecies, while the 

 others mostly resemble (apart from their very different neuration) 

 certain of the more broad-bodied Blennocampids. 



I can vouch from my own experience for all the species enume- 

 rated in Mr. Cameron's " Monograph " as British insects, except 

 temporalis. Of this 1 can only say that I have seen the specimen so 

 called (from Dumfries) in Mr. Cameron's collection at South Ken- 

 sington, and see no reason to question that author's identification of 

 it with temporalis, Thomson (a species otherwise unknown to me). 

 I am acquainted also with two British species which are not men- 

 tioned in the Monograph, unless perhaps they are identical with 

 forms there described as aberrations respectively of flavens and 

 stramineipes. These are wustnei and furstenberqensis (first described 



* The exceptions are Strongyloyaster Jilicis, Klusj, and Thrinax (?) sharpi, Cam.
