 St. Raphael. 



Trichopteryx castanea, Rey. [s intermedial revipennis (Erich.) and 



/'. tericans (lkcr). The elytra arc dark chestnut, very finelj ru ose, and very finely 

 pubescent, etc. 



YillicMorgon ; Cluny. 



Trichopteryx spissata, Rey. — Is rather more oblong, and more convex than /'. 

 sericaw illeer), subsemicylindric, with the elytra moro dilated, and more obtuse at the 

 extremity ; the posterior angles of the prothorax are slightly produced, giving t 

 ance of a true Ptilium.

Trichopteryx subnitens, Rey. — Generally more shining than / ans. It is 



probably a local varii ty. 

 Collioure. 



Trichopteryx opacina, Rey. —Slightly smaller, slightly narrower, deeper and more 

 dull black, and more finely rugose than T. tericans, with th.' antenna; altogether black, and 

 mora sometimes more or less dusky (var. femora is, R.); the elytra are concolorous 

 ami have their sutural angle more straight, etc. 



Lyon ; St. Raphael. 



Pteryx subtruncata, Roy. — This is perhaps a local variety of /'. suturalis iHeer), 

 but nevertheless the prothorax is more contracted behind, the elytra are narrower, more 

 parallel at the sides, more abbreviated and more broadly truncate behind, etc. 



In rotten stumps of pine, St. Kaphael. 



Ptinella elata, Rey. — Very similar to /'. aptera, but the prothorax has two obsolete

The following descriptions are copied from ' L'Abeille,' as I have never seen an 

 authentic example of any of them, and have no means of consulting the original works: — 



P. 60. Hydroscapha granulum. 



Motschulsky, Ktud. iv. 1855, p. 84. 



■■ Nearly twice smaller than Limnebius atomus, and much more strongly attenuated 

 id; black, with the prothorax and elytra reddish-brown or tlavescent ; anteuuie, legs, 

 and (poitrine) pale. Hab. Smyrna." 



Col. Motschulsky appears to have described this insect as a species of Limnebius, but, 

 if it belongs to Hydroscapha, n i< probably an immature form of //. Crotchii. 



V. tiO. Nossidium scaphidiforme. 



Hoch. Bull. Mosc. 1872, ii. p. 215. 



" L. c. 0-5 mm. — Short, oval, rather convex ; pitchy black, shining, slightly pubescent, 

 very closely punctured; elytra abbn ■ of elytra, antenna', and 



ceous. Rather shorter and ii \ than N. pilosellum, but as broad, rather 



more attenuated posteriorly, similar in punctuation, the pubesci nee thinner; prothorax as 

 broad at the base a- the elytra ; elytra nol covering the pygidium, slightly rounded 

 apex, apical margin with the antenna; and legs flavescent. Hal., s. Russia, Kiew."
