NOTES ON COSSONID.^ (2). 



BY G. C. CHAMPION, F.Z.S. 



Tlie following notes arc in continuation of those published anted, pp. 103 — 105. 



Phacegasicr, Woll., type Cntolethrus nasalis, Boh. (cJ), from 

 Brazil. — This genus must be sunk under Catole/hriis,ivom the type of 

 which, C. lon(jiilus, Boh., it chiefly differs in having a much broader and 

 more depressed rostrum in the male. The large, elongate, sub-quadri- 

 foveate ventral depression, and the line of fulvous hair-like scales along 

 the lower face of the femora are, of course, purely male characters, and 

 also to be found in the same sex of C longulus. Gatolethrus longius- 

 culits, Woll., moreover, is the female of C. nasalis, as proved by the 

 series of specimens of that species in the Fry collection. The rostrum 

 oP the male of C./rt/Z«^ is intermediate in form between that of C. 

 long^iJits and that of C. nasalis. A. striking character in this genus is 

 the apically divergent strije of the elytra, a form of sculpture 

 suggestive of that of various Scolytidcs. 



CauJopJiilus sculpturaius, Woll., from Madeira (1854), is synony- 

 mous with C. {Bhi/ncolus) lafinasus, Say (1831), from Florida, as 

 suspected long ago (in 1876) by Leconte. The unique Madeiran 

 type was captured in 1847, and must have been introduced in some 

 way from America. Specimens of 0. lafinasus, from S. Carolina, have 

 recently been sent me by Mr. H. S. Barber, of the U.S. National 

 Museum, and there can be no doubt of the identification of the two 

 insects. Cossonus pinguis, Morn, from Georgia and Florida, is another 

 synonym of the same species, but the insect described by Boheman 

 as R. latinasus is evidently a very different form. Caulophilus extends 

 southward to Mexico and Guatemala, where O lafinasus and one or 

 two other species are found. The larger forms bear a superficial 

 resemblance to Rh/ncolus Ugnarius, Marsh, {cylindrirosfris, Oliv.). 

 The statement in the original description that the wings are obsolete 

 must have been made in error. 



Phloeophagus, Schonh. — The type of this genus is expressly stated 

 to be Cossonus lignarius, Gyll. (nee Marsham) (= P. turbatus, 

 Schonh.), an insect nearly related to Rhyncolus gracilis, Eosenh. 

 {angustus, Fairm.) and the name will have to be sunk as a synonym of 

 Rhyncolus, type R. chloropus, F. (= ater, L.). This fact appears to 

 have been overlooked by WoUaston, and, to avoid substituting a new 

 generic name, his six species of Phloeopliagus from the Canary and 

 Cape Verde Islands, might quite well be placed for the present under
