APPENDIX. 427 



Body narrow, linear, rather flat, sparsely pubescent. Beak parallel, 

 cylindrical, separated from the front by a distinct impression ; eyes rather 

 large, transverse, coarsely granulated, situated on the sides and under sur- 

 face of the head, not visible from above. Antennse inserted about the mid- 

 dle of the beak, short and stout, scape attaining the eyes ; funicle first joint 

 large, 2-7 very short, closely connected, club small, oval, shining, sparsely 

 hairy, annulated only at the tip. Metasternum rather long ; front coxae 

 widely separated, the others still more distant ; tibiae with the terminal 

 hook very large ; tarsi rather short, third joint but little wider, somewhat 

 bilobed. 



The genus has thus far occurred only in Malabar, and Pliolidonotus, 

 which immediately follows it, is found in Borneo. It appears, therefore, 

 to be a third instance of that remarkable distribution which I have pre- 

 viously mentioned in the Heteromerous genera Othnius and Ischalia. 



1. H. errans n. sp. 



Very elongate, reddish-brown, nearly opaque, thinly clothed with coarse 

 yellowish hair. Beak a little shorter than the prothoras, rugosely punc- 

 tured, transversely impressed at the base. Head finely punctured. Pro- 

 thorax more than one-half longer than wide ; widest near the base, sides 

 suddenly rounded behind the widest part, but gradually obliquelj' nar- 

 rowed in front and nearly straight ; slightly constricted near the tip ; 

 disc rather flat, densely and coarsely punctured, without imprtissions or 

 dorsal line. Elytra not wider than the widest part of the prothorax, trun- 

 cate at base, seutellum not visible, sides parallel, rounded at tip ; striae 

 deep and broad, punctures large, quadrate, interspaces very narrow. Body 

 beneath very coarsely punctured ; punctures of ventral segments not 

 smaller. Length 2 mm.; .08 inch. 



District of Columbia ; collected by Mr. Ulke. I owe a specimen of this 

 interesting species to the kindness of Dr. Horn.
