Emmenastrichus gen. nov. 



This name is proposed lor two species which are in 

 all essential respects Emmenastus, except that the surface 

 is sparsely clothed with hair more or less erect. This 

 genus in its relation to Emmenastus parallels that of Pes- 

 cennius to Trim3^t5s, of which mention has already been 

 made. 



The two species known to me are — 



Browuisb, hairs moderately long; thorax with large round, closely placed 

 punctures almost cribrate at the sides. crlbratus. 



Piceous, hairs short; thorax with elongate punctures, denser and deeper 

 at the sides. erosus. 



In both species the elytral epipleura^ are punctate, a 

 character not observed in Emmenastus. 



Emmenastrichus cribratus n. sp. 



Oblong, similar in form to Emmeii. ■punctatiis, brown 

 or slightly piceous. Head with coarse, round punctures, 

 close but not crowded, each bearing a short yellow hair. 

 Thorax not quite twice as wide as long, slightly narrowed 

 in front, sides feebly arcuate, anterior angles prominent 

 in front, hind angles sharply rectangular, base shghtly 

 sinuate, surface with coarse, round, closely placed punct- 

 ures at sides almost cribrate, each bearing a moderately 

 long erect hair. Elytra oblong oval, with stride of coarse 

 closely placed punctures, intervals flat irregularly, biser- 

 iately finely punctate, all the punctures with an erect yel- 

 low hair longer than that of the thorax. Prothorax 

 beneath very coarsely cribrate punctate. Meso- and 

 metothorax similarly but less coarsely punctate. Abdo- 

 men coarsely not closely punctate, surface beneath 

 sparsely hairy as above. Femora punctate. Legs sparsely 

 hairy. Length, .32-. 34 inch : 8-8.5 mm. 



This species might readily be mistaken at first sight 

 for an Amphidora; in fact, one was given to me as such.
