APPENDIX. 3 



also just perceptibly less shining and more finely sculptured, than 

 the other, and has its antennae (if anything) a little shorter and 

 paler ; but the differences are so unimportant, compared with those 

 which separate both forms from the T. velatus, that I do not think it 

 would be safe to treat them as more than phases (possibly indeed 

 mere sexual ones) of a single species. Both of these forms were 

 taken, at a high altitude, by the Messrs. Crotch, in the sylvan dis- 

 tricts of Gomera; and I myself captured two examples of the 

 " typical" state, at Osorio, on the mountains of Grand Canary. 



Genus DROMIUS. 

 Bonelli, Observ. Ent. ii. (1813). 



Dromius plagipennis, n. sp. 



D. elongatus ; capite prothoraceque nitidis, illo rufo-ferrugineo, hoc 

 rufo-testaceo parvo subquadrato ; elytris alutaceis, leviter striatis, 

 fusco-nigris, plaga suffusa testacea in disco antico interno posita 

 (necnon interdum altera minore indistincta versus apicem inter- 

 num) utrinque ornatis; antennis pedibusque testaceis. Long, 

 corp. lin. 3. 



Habitat in Teneriffa et Hierro, in intermediis a DD. Crotch captus. 



Obs. Species D. meridionali, Dej., valde affinis et forsan ejus 

 varietas geographica laetius maculata ; sed prothorax est paulo minor 

 antice sensim angustior, angulis ipsis posticis(oculo fortiter armato) 

 minus rotundatis. 



Eight specimens of the large and beautiful Dromius from which 

 the above diagnosis has been compiled were taken by the Messrs. 

 Crotch, during their late Canarian campaign, one of them at Ycod 

 el Alto in Teneriffe, and the remaining seven (beneath the dead bark 

 of some old props of a fig-tree, in a garden just above Valverde) in 

 Hierro. I feel far from satisfied that they may not be in reality the 

 exponents of some prettily spotted geographical state of the D. meri- 

 dionalis of southern Europe; nevertheless, apart from the bright 

 testaceous blotch on the inner fore disk of each elytron (which is 

 usually supplemented behind by obscure traces of a smaller and very 

 suffused one towards either sutural angle), its prothorax is a trifle 

 smaller (and less widened anteriorly) than is the case in that species, 

 and the extreme basal angles are less rounded. 



Dromius oceanicus, n. sp. 



D. subparallelo -elongatus, subopacus; capite prothoraceque mfo- 

 ferrugineis, illo magno subrotundato in fronte grosse longitudi-
