44 FAMILY II. ANTHRIBID.E. 



36 (9232). CHOKAGUS ZIMMERMANNI Lee., 1876, 408. 



Oval, subcylindrical. Brown, without lustre, slightly pubescent; an- 

 tenna and legs yellow. Thorax densely punctured. Elytra deeply striate- 

 punctate; intervals densely and finely punctulate. Length 1.3 mm. 



Tyngsboro, Mass., July 28. Fort Lee and Hemlock Falls, New 

 Jersey. Ranges from New England to Florida, occurring on 

 sweetgnm, Liquidambar styraciflua L. 



37 (9234). CHOEAGUS HARRISII Lee., 1878, 626. 



"Elongate-oval, subcylindrical. Blackish-brown, shining, finely pubes- 

 cent. Thorax finely, less densely punctate, not opaque. Elytra with deep, 

 coarsely punctured striae; intervals not wider than the strise, scarcely punc- 

 tulate. Length 1.2 mm." 



Detroit, Michigan, one specimen. ''Differs from .: i miner- 

 man ni and xtti/i by being more distinctly (though very finely) 

 pubescent and by neither the thorax nor elytra being opaque." 

 (LcConte.) The types of sayi at Cambridge differ apparently 

 only in size and it is very probable that Jiarrisii will prove to be 

 only a depauperate form of the larger species. 



38 (9235). CHORAGVS NITEXS Lee., 1884, 32. 



Oval, convex. Piceous, shining. Thorax finely punctured. Elytra with 

 the stris fine, distinctly punctured. Length 1 mm. 



Tyugsboro, Mass., one specimen in Blanchard collection. Dis- 

 trict of Columbia on dead twigs. The above brief description was 

 published two years after LeCoute's death by Dr. Horn as editor 

 of his manuscript notes. "Quite different from the other three 

 species in our fauna by the shining surface and smaller size."
