Enterprise and Tampa. This genus exhibits an odd 
mixture of characters. It resembles in form and sculpture 
the new species of Ahexius described below, and has also the 
appearance of Zrichonyz, but it differs from those genera by 
the insertion of the antennee, which are approximate, and 
situate under the frontal protuberance, which is longer than 
in any other genus yet known as belonging to our fauna. It 
resembles, so far as I can judge by the figure and description, 
the Grecian genus Panaphantus Kiesenw. Berl. Ent. Zeitschr.

22. Rhexius substriatus, n. sp. —Larger, darker and less convex 
than R. insculptus. Head with two fovee and a frontal impression ; occiput 
very finely carinate ; eyes small. Prothorax finely channeled, with three 
large impressions near the base. Elytra with basal margin elevated, post- 
basal fovez deep, each with four faint strise, of which the sub-sutural one is 
longer and more distinct, the others extending only to about the middle. 
Antenne with the 9th and 10th joint less suddenly larger than in R. in- 
sculptus. Length 1.5 mm.; .06 inch. 
lampa, April, one specimen, under old leaves. 
23. Trimium convexulum, n. sp.—Pale rufo-testaceous, shining, 
slightly pubescent. Head with a large deep angulated impression, front 
concave, occiput convex, smooth. Prothorax longer than wide, convex, 
subeordate, rounded on the sides in front, then narrower and broadly 
sinuate; dise sooth, with a transverse impression near the base; this 
impression is slightly angulated at the middle, and extends on the sides, 
but does not terminate in a lateral fovea, as is the case in 7. parvulum. 
Elytra convex, deeply bifoveate at base, sutural stria faint, dorsal one 
short. Length 7 mm.; .028 inch. 
lampa, May, one specimen. I have one quite similar 
from Illinois. Mr. Ulke has received specimens from Ten- 
nessee. 
34. Trimium californicum, n. sp:—Allied to T. globiferum, 
but larger and stouter, bright red-brown. Head with an angulated im- 
pression ending behind in two large fovee ; occiput convex, smooth. Pro- 
thorax rather wider than long, not very convex, narrower behind ; fovese 
large, connected by a deep transverse line. Elytra nearly twice as wide as 
the prothorax, sparsely punctulate ; basal fovese small, sutural stria deep, 
dorsal fine, extending for two-thirds the length of the elytra. Antenne 
with the last joint ovate, acute at tip, not so large as in T. globiferum. 
Length 1.9 mm.; .05 inch. 
California, a specimen kindly given me by Dr. Horn.
