the little terminal joint been overlooked ; and the ninth, which is 

 nearly as large as the eleventh, been regarded as one of the three 

 forming the club ? 



Alth^esia [Mycetophagidae]. 



Head deeply inserted in the prothorax, triangular, slightly dilated below the 

 eyes. Antennae longer than the prothorax, eleven-jointed, the last three 

 forming an oblong perfoliate club. Eyes large, round, very prominent, 

 rugose. Maxillary palpi with the second and third joints thickest, the 

 terminal obconic, truncate ; the labial short, triangular, approximate. 

 Maxillary lobes narrow, nearly equal. Prothorax transverse, narrower 

 and slightly emarginate in front, rounded at the side, the base bisinu- 

 ated. Elytra slightly convex, margined, the base closely applied to 

 the prothorax, but enlarging behind the shoulder, then rounded to the 

 apex. Legs moderate; coxae distant; tibiae fringed externally, en- 

 larging towards the extremity, and terminated by four or five short 

 spines; tarsi slender, hairy beneath, four-jointed, the anterior with the 

 penultimate very indistinct (male only ?). 



Eesembles Mycetophagus in outline, but with a triarticulate club, 

 and large round, very rugose and prominent eyes.
