CANARIAN COLEOPTEBA. 411 



femora are also dark), have an occasional tendency to become clouded 

 about tbeir disc, suture, and shoulders ; and in one or two highly 

 coloured specimens (out of many hundreds which I possess) the discal 

 cloud assumes the form of a well-defined patch (and even the hu- 

 meral one is somewhat concentrated) — thus causing them to re- 

 semble very much the paler examples of the L. persimilis. Such 

 individuals, however, are extremely scarce ; and even in them the 

 lighter sculpture prevails (as in the ordinary ones); and therefore, 

 in spite of their prima facie approach to the last species, I must re- 

 gard their connectiveness as more apparent than real. So far as I 

 have observed hitherto, the present Longitarstis is exclusively at- 

 tached to the fragrant Messersclimidtia fruticosa — on which shrub, 

 when carefully examined, I have scarcely ever failed to detect it. 

 Its range is consequently somewhat lower than that of the L. per- 

 similis, which feeds on the Ecliia of more lofty elevations. I have 

 taken it abundantly in the waste grounds above the Puerto Orotava, 

 as well as between Ycod de los Vinhos and Garachico, of Teneriffe ; 

 on the rocks between the plains of Los Llanos and the Pinal, in the 

 Banda of Palma ; and a little above the sea-coast, in the district of 

 El Golfo, on the west of Hierro."

Habitat in Fuerteventura, Canaria et Teneriffa, minus frequens. 



The common European L. ochroleucus, so well distinguished by its 

 small, laterally rounded, almost unsculptured pro thorax, its very finely 

 punctulated elytra, and its excessively pallid, whitish-testaceous 

 upper surface (the antennaj alone, except the basal joints, and the 

 apical half of the two hinder femora being dark), appears to be both 

 local and rather scarce in these islands — into which it may very 

 likely have been introduced from more northern latitudes. I have 

 taken it in Grand Canary (on the mountain-slopes above San Mateo, 

 on the ascent to the Roca del Soucilho), and also around Orotava 

 and S'" Cruz, as well as at the Agua Garcia, in Tcneriff'e — in the 

 latter of which islands it was found also by Dr. Crotch. 



After a more careful comparison of the specimen (captured by Mr. 

 Gray in Fuerteventura) which I described, in 1860, under the spe-
