182 Mr. D. Slidipb Cuntrihutions to the 



fifteen or sixteen punctures, each patch consisting of three 

 inclistinct ol)li(iuc rows. Tliorax just about as broad as 

 the head and elytra, its -width distinctly greater than its 

 length; it is a little narrowed behind, and has on each 

 side sixteen or eighteen ])unctures irregularly scattered; 

 the middle space between these piuictures nnich narrower 

 at the back part than in front. Elytra longer than the 

 thorax, ]Htchy black, finely and not closely punctured. 

 Hind body parallel, rather coarsely but not densely punc- 

 tured. Legs pitchy. 

 Ega ; two specimens.

 antennis ])edibusque testaceis, thorace concavo, elytris 

 dense subtiliter punctulatis. Long. coq). l.^ lin. 



Antennae considerably longer than the head, yellow ; 

 3rd joint scarcely longer than 2nd, 6 — 10 a little trans- 

 verse. Mandibles and palpi yellow. Head pitchy, broad, 

 even a little broader than thorax or elytra ; the length 

 about as great as the Avidtli ; the hind angles considerably 

 rounded; the upper surface sparingly and irregularly 

 punctured, the punctui-es leaving scarcely any distinct 

 smooth space in the middle. Thorax as broad as the 

 elytra, about as long as broad, narrowed behind, the sides 

 rounded ; it is of a pitchy-yellow colour ; the wliole of the 

 upper surface concave, sparingly and irregularly punc- 

 tured. The elytra are longer than the thorax, finely and 

 closely punctiu'cd, of a pitchy-yellow colour, their disc 

 concave. Hind body pitchy yelloAv, rather finely, mode- 

 rately closely pimctured. Legs yellow. 



Ega ; one specimen. 



Obs. — This individual is a little immature, so that the 

 colour of the species maybe somewhat darker than is here 

 described, and it is probable that -when fully develo))ed 

 the elytra may be Avithout imjH-ession, but I expect the 

 thorax is naturally concave on the upper surface. 



4. Holisus umbra, n. sp. Omnium perdepressus, an- 

 gustus, nitidus, piceus, antennarum basi, pedibus, anoque
