1886.] REV. H. S. GORHAM ON NEW COLEOPTERA. 159 



Mas. Tibiis anticis dente acuto, adjacente, infra medium ; intermediis 

 apice incurvato, posticis leviter sinuatis. 



Hah. Madagascar (Gowaii). 



Entirely black, subopaque above, body beneath shining. Antennae 

 rather short, a little longer in the male than in the female, tlieir 

 club not very wide nor abrupt ; head rather uneven, with a few 

 scattered obsolete punctures. Thorax half as wide again as long, 

 opaque ; punctuation very obsolete, minute and scarcely visible, 

 basal sulci distinct ; front angles very little produced, scarcely at all 

 in the female, sides nearly straight, base finely margined. Elytra 

 half as wide again as the thorax and slightly widened behind, callus 

 only faintly raised. The male specimen has two minute red dots 

 near the apex of the elytra, in the female they are wanting. Meta- 

 sternum (in male) depressed between the hind coxae, and first ven- 

 tral segment with scattered small punctures. 



Two specimens from Dr. Sharp's collection. 



Anidryttjs, Gerst. 



1. AnIDRYTUS aUADRIPUNCTATTJS. 



Oblongus, parum ovatus, rufo-piceus, nitidus, crebre subobsolete 

 punctatus, cupreo-pubescens ; antennis nigris, articulis quatuor 

 basalibus et apice summo rufis ; prothorace punctis quatuor 

 discoidalibus nigris. Long. 8 millim. 2 . 



Hab. Brazil, Blumenau. 



Head finely punctured, a little rugulose between the eyes ; hasal 

 and three following joints of the antenniB pale ferruginous, the 

 fourth joint being deeper in colour, and at its articulation with the 

 third nearly black. Thorax just twice as long as wide, from the 

 front angles the sides are very evenly rounded to near the base, where 

 they become straight. The basal furrows are two distinctly 

 impressed, converging, linear channels ; within them, where they end 

 on the front of the disk, halfway between the base and the front 

 margins, are two round black points (as in A. bipunctatus) ; more in 

 front and more widely apart are two other black points. The disk 

 and sides of the thorax are evenly, thickly, not confluently punctured, 

 but the surface of the black spots is smooth, or in the external spots 

 with one or two punctures only. The elytra are somewhat parallel, 

 not strongly convex, evenly and more thickly punctured ; the punc- 

 tures are (as is usual where they give rise to hairs) not pricked in, 

 but irregular, somewhat linear, and flat-bottomed. Legs clear red, 

 only a very little darkened at the base of the tibiae. The underside 

 wholly ferruginous red. 



Although this appears to be a species very nearly allied to A. 

 bipunctatus, Gerst. (a species also from Brazil), the description 

 given above will show that it differs not only by the four black spots 

 of the thorax, but by the colour of the underside and legs as well. 



I have only seen one specimen, a female, which was sent to me by 

 Herr Eeitter, with other Coleoptera collected in the same district.
