59. Adinopsis rufobrunnea, n. sp. 



Minute, obscure reddish brown, the elytra (in one specimen) and 

 the first four visible segments of the abdomen blackish; densely 

 and finely punctured and pubescent throughout, scarcely shining; 

 antennae, mouth-parts and legs testaceous. Length l - 4 mm. 



.Similar in scheme of coloration to D. cinnamomea, Kr.. from Ceylon, 

 but much smaller and narrower. Head transverse, convex, the eyes 

 small, the temples passing insensibly into the base; puncturation 

 exceedingly fine and close, pubescence very fine. Antennae long 

 and slender, the 1st and 2nd joints of about equal length, stouter 

 than the following, the 3rd shorter than the 2nd, the 4th longer than 

 the 3rd. the 4th to the 11th all elongate and differing but little in 

 length, the 12th slender, subulate, almost as long as the 11th. 

 Thorax transverse, convex, widest posteriorly at the rectangular 

 posterior angles, from thence gently rounded and narrowed to the 

 obtuse anterior angles; posterior margin bisinuate, making the 

 hind angles a little prominent; puncturation close, line, but rather 

 rough, pubescent fine, yellowish. Scutellum concealed. Elytra 

 about as long as, but narrower than, the thorax, transverse, pretty 

 deeply emarginate internal to the postero-external angles, from 

 thence obliquely truncate to the suture; puncturation and pubes- 

 cence similar to that of the thorax. Abdomen pointed, margined, 

 the first four visible segments blackish, the last two reddish-testace- 

 ous ; puncturation dense and fine, more sparing on the last two 

 segments; pubescence dense and tine, almost sericeous; anal styles 

 of equal length, the lateral stouter than the median. Sides of the 

 abdomen and tibiae not setose.
