margins sometimes extending to anterior row of teeth ; surface sparsely 

 clothed with short, semierect, yellowish hairs, which are longer to- 

 ward margins, basal half coarsely, densely, but not confluently ocel- 

 late-punctate, the punctures fine and slightly asperate at middle, 

 apical half with concentric rows of broad, sharp, rasplike teeth, the 

 two median ones on anterior row contiguous at bases and longer than 

 lateral ones, the intervals between teeth finely, densely ocellate-punc- 

 tate. , 



Elytra twice as long as pronotum; sides slightly expanded pos- 

 teriorly; sutural margins on apical declivity slightly elevated; sur- 

 face sparsely clothed with short, erect, rather stiff, yellowish hairs, 

 densely, coarsely, uniformly ocellate-punctate, the punctures dis- 

 tinctly separated on apical declivity, intervals finely, densely granu- 

 lose. 



Body beneath densely, finely granulose, rather densely clothed with 

 long, recumbent, yellowish hairs ; first segment of anterior tarsus dis- 

 tinctly longer than either the third or fourth segment, and clothed 

 with long hairs. 



Length 3-4 mm., width 1.2-1.5 mm. 



Type locality. — Japan, no definite locality ; type in Paris Museum. 



Distribution. — This species has been recorded from Japan, China, 

 and Australia. Specimens have been examined from bamboo, which 

 was intercepted at the following localities : 



Arizona : Tucson, March 20, 1939 (L. P. Wehrle) . 

 California : San Jose, October 10, 1914 (G. B. Howard). 

 Georgia : Savannah, August 2, 1937. 



Illinois : Urbana, February 8, J 933 (Mohr and Waldron). 

 Maine : Augusta, January 12, 1932 (H. P. Peirson). 

 Massachusetts : Melrose Highlands, April 6, 1923. 

 Missouri : St. Louis, July 25, 1942 (B. D. Brayton) . 



Host. — Bamboo. 



Lesne (1895) described this species from a unique specimen in the 

 Paris Museum without mentioning the number of segments in the 

 antenna. In 1898 he placed it with the species having 10 segments in 

 the antenna, but in 1914 placed it in his new subgenus Dinoderastes, 

 stating that the antenna was composed of 11 segments. Matsumura 

 (1915) described a species of this genus from Japan under the name 

 of tsugae, but Chujo (1936), after examining the type, placed it as a 

 sjmonym of japonicus Lesne. 



Dinoderus pubicollis Van Dyke 



Dinoderus puMcollis Van Dyke, 1923, Brooklyn Ent. Soc. Bui. 18: 45-46; Lesne, 

 1938, in Junk (pub.), Coleopt. Cat., pt. 161, p. 25. 



Since the writer has not examined the type of pubicollis, and the 

 species is placed in the key solely upon the characters given in the 

 original description, it seems advisable to include the following copy 

 of the original description : 



Cylindrical, moderately short, somewhat shining, piceous, antennae rufous and 

 tarsi rufo-castaneous. Head with long fulvous hairs about mouth-parts and 

 on basal joints of antennae, regularly rather closely and deeply punctate and 

 strigose posteriorly ; the antennae eleven-jointed, the first joint large, the second 

 almost spherical and narrower and about one-half length of first, the first and 

 second joints of club transverse, the last about as long as broad. Prothorax as 

 broad as long, the anterior half with six concentric rows of sharp rasplike 

 teeth, the individual teeth more or less united and more prominent in front,
