276. Laparocerus morio. (Tab. VII. fig. 1.) 



Ij. oblongo-ovatus convexus niger vel piceo-nigcr, pubc subtilissima cinerea parce tectus, prothorace 

 valde convexo sat crebre punctulato, elytris punctato-striatis, interstitiis plus minusve obsole- 

 tissime longitudinaliter subopalino-cinereo-tessellatis et tuberculis minutissimis remotis obsitis, 

 antenuis tarsorumque apice ferrugineis. 

 Mas, pedibus robustis latis : tibiis intus crenulatis ; anterioribus apice robuste uncinatis ; anticis 

 ad apicem incurvis; posticis apicem versus facile dilatatis, angulo interno late arcuato-emar- 

 ginato (calcaneum rotundatura longe pone apicem efBciente), externo subrecto valde setuloso 

 le\iter exstante. 

 Fam., paulo niiuor; pedibus graeilioribus brevioribus : tibiis intus obsoletissime crenulatis et apice 



valde indistiucte uncinatis ; anticis ad apicem leviter incur\'is ; posticis simplicibus. 

 Variat colore et statur4 generali : hac vel oblongo-ovata evidentius subtiliter pubescente, vel majore 

 suboblonga fere glabra ; illo jam nigro, jam piceo-nigro pedibus infuscatis, jam (immaturo) etiani 

 oinnino fusco-ferrugineo.

Laparocerus morio, Schon. Gen. et Spec. Cure. ii. 531 (1834). 



Habitat sub lapidibus insularuni omnium Maderensiuni, ab ora maritima usque ad summos montes 

 ascendens : in insulis Desertis, Boreali et Grandi (prajsertim hac), amplitudine accrescit, qua 

 mense Januario e fissuris rupium excelsaruiii, una cum insectis quibusdam heteromeris degeus, 

 copiosissimc collegi. 



L. oblong-ovate, or nearly oblong (being at times comparatively parallel), convex, black, or piceous- 

 black, (when immature of a dull ])rownish-fcrruginous hue,) and more or less sparingly clothed 

 with an exceedingly minute, decumbent, cinereous pubescence, — wliich is occasionally nearly 

 absent. Rostrum short, and narrowed anteriorly; longitudinally strigulose; and with a very 

 deep impression, or abbreviated channel, between the eyes, — which are subrotundate. Prothorax 

 extrcnu-lv convex (in some specimens almost subglobose), with the sides regularly and equally 

 rounded, being widest about the middle ; sufficiently closely, but not very deeply punctured, the 

 spaces between the punctures being densely beset with most minutely and delicately impressed 

 points*. Elytra either ovate or suboblong, more or less deeply punctate-striated ; the inter- 

 stices very minutely rugulose, studded, especially behind, with small and distant tubercles, and 

 with a very faint tendency (sometimes comparatively evident, at others scarcely distinguishable) 

 to be longitudinally tessellated with paler portions of the pubescence, which often assume a 

 slightly subopalinc hue, — the cinereous scales being just perceptibly tinged with a bluish-, or 



• When viewed beneath the microscope, this sculpture is of a very peculiar character, — the larger 

 pmictures throwing out radiating lines which almost meet, and which, in conjunction with the minutely 

 impressed intermediate points, give the surface a somewhat rugulose appearance.
