HELP-NOTES TOWARDS THE DETERMINATION OF BRITISH 



TENTEREDINID.E, &c. (21). 



SELANDRIADES (pars) RARPIPRORUS and ATHALIA. 



RT THE REV. F. D MORICE, M.A., F.E.S. 



The genera placed by Konow in his tribe Selnndriades form a 

 part only of those called Selandriades by Thomson, the latter including 

 also Konow's Hoplocampides and Blennocampides. Most of these 

 genera are very distinct and easily recognised ; and the species 

 contained in them are also, generally, not difficult to determine, their 

 characters being such as can be seen sufficiently, even in damaged or 

 ill-prepared specimens. But to this there is one notable exception, 

 viz., in the genus which is commonly known as Pascilosoma, Dhlb., 

 and which I have so called in these papers hitherto, but which Herr 

 Konow now tells me should bear the name of Empria, Lep. {of. Lep. 

 St. F.. Hist. Nat., plate 47, fig. 3). Here we have species whose 

 determination requires us in many cases to examine minutely parts 

 which a bad condition or preparation of the insect may hopelessly 

 conceal, such as the claws, the genae, and (above all) the form and 

 sculpture of the clypeus. 



The alar neuration in this group differs a good deal in the 

 different genera, and also in the different species. Thus the hind- 

 wings may have two "closed cells " (cubital and medial), or owe only, 

 or none at all ; and in one species of the genus Taxonus the $ £ show 

 what I have called " continuous external neuration " (Ent. Mo. Mag., 

 1903, p. 53, fig. G). 



In all cases, however, the basal n. of the fore-wing is received 

 very near the origin of the cubitus, and its direction is more or less 

 parallel to that of the 1st medial n. (i. e., they do not converge towards 

 the base of the stigma as in the Hoplocampids and some Blenno-
