Synopsis of the Coleopterous Famih/ Cisidae (Cioidae) 21 



Braclu/cis brericollis, Csy. 



To the original description, Journal New York Ent. Soc., 

 p. 86, vol. vi, I add the following: The male has a large cir- 

 cular cicatrix like fovea, a little posterior to the middle of the 

 first ventral segment. The original generic diagnosis says 

 "tlTt" side margin of prothorax is obsolescent at apical angles." 

 In seventy-five specimens examined, this margin is sharp and 

 strongly developed around these angles. The front tibiae are 

 produced into a spur at apex and the middle and hind tibiae are 

 oblicjuely truncate and spinulose. My specimens average 1-07 x 

 0-8 mm. in size. North Illinois and Mobile, Ala., from which 

 latter place I have bred them from fungus sent by Mr. 

 Loding. They are very abundant in Alabama, but I have not 

 yet found them at Cincinnati. 



Plesiocis crihrum, Casey 



The description by Casey evidently refers to the female. 

 Some of my smaller females fit this description closely. The 

 males have strong secondary sexual characters. The reflexed 

 epistoma is quadridentate; the prothorax is produced at 

 apex into two short processes, with a broad, shallow emargi- 

 nation between them. The first ventral segment has a sharp, 

 small, round fovea at middle. The females range in size from 

 less than 2 to 3.50 mm. Fourteen specimens. Truckee, Cal., 

 also Humboldt and Sonoma Countie$. 



ENNEARTHRON, Mellie 



Ennearthron compacta, n. sp. 



Short, round, thick and compact. Color piceous black, 

 glabrous and shining. Head with epistoma rounded and front 

 transversely sulcate. Prothorax about as wide as long. Sides 

 rounded and margined around front angles, which arc ]>romi- 

 nent. Apex produced into a thin lamelate process, emarginate 

 at tij). Punctures very uniform, sparse and fine. Elytra one 

 and one-half times as long as wide, with punctures closer and
