1892.] PHYTOPHAGOUS COLEOPTERA FROM MADAGASCAR. 567 



EULYCHIUS NIGRITARSIS, n. Sp. 



Fulvous, the terminal joints of the antennae and the tarsi black ; 

 thorax rather sparingly punctured ; elytra strongly punctate-striate ; 

 femora dentate. 



Length 2 lines. 



Head finely and sparingly punctured, the vertex convex ; clypeus 

 finely rugosely punctate, separated from the face by a transverse 

 groove, eyes surrounded by a very narrow sulcus; antenna extending 

 a little beyond the base of the elytra, fulvous, the apical five joints 

 black, strongly dilated and transverse, the third, fourth, and fifth joints 

 equal, the sixth shorter ; thorax transverse, the sides rounded, the 

 anterior angles rather acutely produced, the surface finely and not 

 very closely punctured on the disc ; elytra not depressed below the 

 base, distinctly punctate-striate, the punctures much finer towards 

 the apex ; femora with a small tooth ; the extreme apex of the tibise 

 and the tarsi black. 



This species, like E. dorsalis, Duv., differs from the type in having 

 armed femora ; the transverse apical joints of the antennge are, 

 however, typical. The black tarsi and general system of coloration 

 separate the present insect from the other two known species. 



Pheloticus brunneus, n. sp. (Plate XXXIX. fig. 2.) 



Broadly ovate, robust, dark fulvous ; the antennae (basal joints 

 excepted), the knees, and the apex of the tibiae black; thorax 

 subcorneal, very sparingly and finely punctured ; elytra finely 

 punctate-striate anteriorly only ; femora minutely toothed. 



Length 3g lines. 



Head impunctate, the eyes with a very narrow sulcus at their 

 inner margin, rather deeply notched, the epistome not separated 

 from the face ; jaws black ; antennae slender, filiform, extending to 

 nearly two-thirds the length of the elytra, black, the lower four 

 joints fulvous, the third and fourth joints equal ; thorax subconical, 

 narrowed in front, the sides nearly straight ; the disc about one 

 half broader than long, with a few fine punctures at the sides ; 

 scutellum smooth, subpentagonal ; elytra much broader at the base 

 than the thorax, convex, with a very shallow basal depression ; the 

 shoulders prominent, bounded within by a longitudinal depression ; 

 the disc with a few rows of fine punctures distinct only anteriorly, 

 nearly obliterated below the middle ; underside and legs fulvous, 

 the apex of the femora and of the tibiae as well as the claw-joint 

 black ; femora with a small tooth ; tibiae not channelled, the four 

 posterior ones deeply emarginate before the apex ; claws appen- 

 diculate, the inner division very short and pointed ; prosternum 

 slightly longer than broad, concave, deeply punctured, the thoracic 

 episternum strongly convex. 



A rather aberrant species and not typical of Pheloticus or allied 

 genera, apparently allied to P. seripunctdtus, Fairm., but differing 

 in the colour of the antennae and legs.
