608 INSECTA MADERENSIA, 



l)eiuij often found amongst wet mud and decaying vegetable refuse at the edges of 

 ponds and streams. I have taken it in the neighboiu'hood of Funchal, dm-ing the 

 spring ; and at Santa Anna, in July, — though in the latter locality only at the 

 margin of a small rivulet on the descent from the Quinta of Senhor Louiz Acciaioly 

 to the sea. It occiu-s throughout the whole of Europe, and is mentioned by Erich- 

 son as having been brought from Egypt and South iVmerica. 



475. Oxytelus complanatus. 

 O. iiiger subopacus, capite, prothorace elytrisque creberrime longitudinaliter strigulosis, his interdum 

 obscure fuscescentibus, pedibus diluto-testaceis. 

 Mas, capite prothoracis latitudine : abdominis segmento sexto subtus ad apicem obsolete trisinuato, 

 necnon apicem versus parte media transversa crassiore elevata clypeiformi postice emarginata 

 (quasi e tuberculis duobus magnis basi confluentibus formata) aucto ; septimo late emargiuato. 

 Foem., capite prothorace angustiore : abdominis segmento sexto subtus truncato ; septimo in medio 

 triangularitcr producto.

Habitat ]\Iadcram, ab ora maritima usque ad summos montes ascendens : in ipsa urbe Funchalensi 

 abundat, qua tempore screno per aerem volare srepissime videatur. 



O. black, and greatly depressed. Head, prothorax and elytra nearly opake, and most densely and 

 minutely longitudinally-strigulose : the first with an indistinct and very abbrenated central 

 channel (or fovea) behind, and also with obscure indications of lightly impressed punctures on 

 its posterior portion ; with its extreme edges slightly raised (except quite in front), straightened 

 over the eyes, but regularly rounded off (the anterior angles being scarcely at all defined, and 

 liartUy even elevated) into the region of the clypeus (which is a little depressed) : the second with 

 its angles rather more defined, or acute, than in the other species ; trisulcated down the disk 

 (the central groove being narrowed behind, and the outer ones flexuose) ; and both widely and 

 deeply impressed towards either side : the last of a rather less intense black than the head and 

 juothorax, — being usually somewhat brownish or pieescent posteriorly. Arttenna considerably 

 shorter than the head aud prothorax, black. Legs testaceous, — the femora being sometimes 

 obscurely infuscated. 



Male, with the head about as wide as the anterior region of the prothoFax. The abdomen beneath 

 with the sixth segment minutely waved, or trisinuatcd, at its termination, aud iucrcascd behind 

 the apex (in the centre) by a transverse, thickened, elevated, clypeiform, but apically emarginated, 

 portion (as though produced by two large tubercles, — confluent, and conjointly elevated, at their 

 base) ; and with the seventh widely emarginated. 



Female, with the head a little narrower than the prothorax. The abdomen beneath with the sixth 

 segment truncated; and with the seventh somewhat triangularly produced in the centre.
