emarginate in front; the ocular canthus not much encroaching upon the 

 eyes. Antennas rather short, thickest at the eighth joint, so that their 

 general outline is somewhat fusiform. Thorax very little broader than 

 the head across the eyes, a little narrower behind; very distinctly but 

 not very thickly punctured; the angle obtuse; the sides somewhat 

 straight, very finely margined. Elytra as wide as the broadest part of 

 the thorax, parallel, their surface somewhat uneven or wrinkled; each 

 elytron with four or five scarcely impressed lines, with somewhat large 

 punctures, the lines somewhat irregular, or here and there interrupted. 

 Legs rather slender. (Water house.) 



Length, 2.5 to 2.75 mm.; width, 0.65 mm. 



It will be noticed by the references to the genus that Water- 

 house's characterization has been transcribed in the Journal 

 of the New York Entomological Society; hence, need not be 

 repeated. 



Distribution. The type of this species was found in rice 

 from Calcutta, India. The insect is also recorded from 

 Arabia, Norway, and England. Champion has added its 

 occurrence in Italy, in a London granary, in samples from Bus- 

 sorah, Persia, and Odessa, Russia. The genus, as might be 

 inferred from the illustrations of the species presented here- 

 with, is closely related to Tribolium; in fact, it is placed near 

 the head of the tribe Ulomini, directly after Hypophhviis and 

 Doliema. This brings it above Ctcnocorse (JPalorus) and 

 Tribal in m. 



The occurrence of this genus in the United 

 States was recorded only a few years ago (see 

 reference by the writer above quoted), but the 

 species under consideration, oryzcc, was not recog- 

 nized here until 1908. January 16 of that year 

 Mr. D. K. McMillan, of the" Bureau of Ento- / 

 mology, U. S. Department of Agriculture, work- f 

 ing under the writer's direction, found this 

 species at Houston, Texas, in corn in a mill 

 there. It was not observed in abundance and 

 was associated with other mill and grain insects. 

 Later the same species was received from New 

 Brannfels, July 3, in flour, July 25 in rye and elevator 

 sweepings; in mill material from San Antonio; grain from Gal- 

 veston; wheat and mill material from Fort Worth; wheat, 

 grain, and refuse from Lyons and Wichita Falls, Texas, prac- 

 ticallv all collected by Mr. McMillan. 



In February, 1910, Prof. R. H. Pettit sent a number of this
