Dec, igiS-] SCHAEFFER : New CoLEOPTERA. 237 



Staten Island, N. Y. Mr. Charles Leng also informs me that his son 

 found it abundantly in July at the latter locality and Mr. Davis has 

 specimens in his collection from Clove Valley Staten Island, Aug. 3, 

 191 1. In New Jersey it was found by Mr. E. L. Dickerson in a com- 

 mercial nursery and by Mr. F. M. Schott at Moonachie, March 14, 



1915- 



Two species of Plagiodcra as far as I know, occur now within the 

 limits of the United States. The above-mentioned species P. versi- 

 color Laich, and P. thymaloidcs Stal. The first has the upper surface 

 blue, bluish-green or green, shining, the antennae are black except the 

 first five joints, which are brownish, the prothorax is more finely 

 punctate than the elytra. P. thymaloidcs Stal. from Brownsville, 

 Texas, is pale reddish-brown beneath, head and thorax of the same 

 color except that the latter has a dark brownish central spot, the 

 elytra are dark brown with a slight metallic tint and the lateral 

 margins are pale reddish brown, the first five antennal joints are pale 

 reddish brown, the others black, the prothorax is almost smooth at 

 middle with a few moderately coarse punctures at sides, the elytra are 

 relatively sparsely, irregularly punctate, the punctures rather coarse. 



These two species are true Plagiodcra, those listed in the Henshaw 

 list under that name and in Blatchley's Coleoptera of Indiana belong 

 in the genus Phccdon. In Plagiodcra the elytral puctuation is confused 

 not in regular series, and the elytral epipleurae are excavated, in 

 Phccdon the elytral punctuation is in regular series and the epipleurse 

 are not excavated. 



Family TENEBRIONID.F:. 



Rhacius SUlcatulus Champ. Biol. Cent. Am. Col., Vol. IV, pt. i, p. 121. 



A single specimen, collected by the late Ottomar Dietz in Browns- 

 ville, Texas, agrees with the description of this interesting Mexican 

 species. It looks somewhat like a robust Tcnchrio castaneus Knoch. 

 The position of the genus Rhacius is rather doubtful; it seems to be 

 near Tcnchrio and allies but the absence of a coriaceous hind margin 

 to the third and fourth ventral segments exclude it from the subfamily 

 Tenebrionin^e. 



Sitophagus hololeptoides Cast. 



The late Ottomar Dietz took in Brownsville, Texas, a few speci- 

 mens of this species which is widely distributed in tropical America 

 from Mexico to Brazil and Cuba.
