448 INSECTA MADERENSIA. 



paler than the prothorax, and less rufescent, — being of rusty brownish-testaceous ; and rather 

 coarsely punctured, — the punctures having a slight tendency to be disposed in rows. Body 

 beneath (except the prothorax), and the apical half of the hinder femora, picescent. Antenna at 

 apex very slightly infuscated. 



The minute size of this somewhat insiguificant Longitarsus would be sufl&cient, 

 even alone, to separate it from the remainder : nevertheless its reddish-ferruginous, 

 or rusty-testaceous, hue, its obsolete wings, and its comparatively deeply punc- 

 tured elytra, — the pitnctures of which are a little inclined to be disposed in rows 

 (of very rare occurrence in the present genus), — will afford additional characters 

 whereby to distinguish it. It is in some respects allied to the L. BallotcB of 

 Marsham, in which the wings are, also, obsolete and the elytral pitnctures have a 

 slight tendency to longitutlinal distribution ; nevertheless its smaller bulk, darker 

 and more rufescent hue, and (especially) its almost unsculptui'ed prothorax, Avill 

 readily remove it from that species (in which that portion of the surface is inva- 

 riably as coarsely punctulated as the elytra). It is exceedingly scarce, the only two 

 specimens which I have seen having been captured l)y myself, — one on the 19th of 

 July 1850, at the extreme head of the Ribeiro de Joao Delgada, al)out 5000 feet 

 above the sea ; and the other in the remote forest district of the Lombo dos Pece- 

 gueiros, during the same montli.

 A.D. 1831) may be easily recognised by the thicker and more elliptical bodies of 

 the species composing it, by their comparatively small heads and anteriorly- 

 attenuated prothorax, and by the construction of their two hinder legs, — which 

 have the femora enormously incrassated, and the tibiae obliquely scooped out (or
