Leptotomus Pittieri, sp. n. 



Subovatus, rufo-brunneus ; pronoto nitido, medio longitudinaliter 

 inipresso, lateribus paullo rotundatis. angulis anticis acutis, 

 posticis subobtusis, margine basali leviter bisinuata ; elytris 

 longitudinaliter tenuissimeque striatis, utrisque serie marginali 

 punctorum setigerorum. 



Long. 6, lat. 3 mm. 



Hah. Costa Rica, Buenos Aires (H. Plttier). 



Short and somewhat ovate in form ; reddish brown in 

 colour. Head and prothorax glossy. Elytra more opaque, 

 but exhibiting a soft silky lustre in certain lights ; impressed 

 with very fine and close- set longitudinal striae, running 

 parallel to one another, and only visible with the aid of a 

 good lens or low power of the microscope ; each elytron has 

 a row of rather widely separated setigerous punctures close 

 to the outer margin. 



Menidius vittatus, sp. n. 



Capite protboraceque ferrugineis, elytris flavo-testaceis, vittis nigris 

 ornatis — una suturali, una submarginali et subsinuata, una ab 

 suturali ad margin alem oblique transeunte, una per medium 

 discum a basi ad fasciam obliquam descendente. 



Long. 7, lat. 2| mm. 



Hob. Costa Rica, between Mata de lana and Rodeo, on 

 the Pacific side. 



This species has a close resemblance to M. circumseptus, 

 Bates, but the sutural vitta extends right up to the scutellum, 

 and there stops, instead of bifurcating and circling round the 

 base of each elytron ; there is, in addition to the submarginal 

 black line, another which runs along the middle of each 

 elytron from the base as far as the oblique fascia which 

 joins the sutural with the submarginal vitta ; the latter is 

 somewhat removed from the margin in its anterior half, but 

 beyond the middle, where the oblique fascia joins it, bends 

 downwards and approaches the margin much more closely ; 

 at the junction of the oblique fascia with the sutural vitta at 

 about the beginning of its posterior third there is a slightly 

 expanded rhomboidal black area. 



The prothorax is transversely strigose above, and is im- 

 pressed with a median longitudinal groove. 



Scarabaeidae. 



Copris costaricensis, sp. n. 

 Oblongus ; clypeo antice leviter emarginato ; thoracis angulis anticis
