Sijnopsis of the Coleopterous Faniili/ Cis-idac {Cioidac) 19 



Strigocift opacicollis, n. s]). 



Elongate, oval. Color ])iceous. Legs and antennae pale. 

 Thorax opake and alutaceus, not closely, but rather strongly 

 punctate. As wide at base as apex. Front angles prominent; 

 sides feebly arcuate. Strongly margined at base and sides to 

 apical angles. Elytra more shining than prothorax and nearly 

 twice as long. INIoderately and uniformly i)unctured, each 

 puncture bearing a light colored bristle, arranged without 

 order. The humeral callus very ])rominent, shining and resem- 

 bling a roimded tubercle. Suture finely margined more strongly 

 behind. In the male the clypeus is projected forward in a thin 

 broad bifercate ]>rocess, behind which the front is deeply 

 excavated into a rounded depression. The apical edge of 

 ])rothorax is prolonged into an abrupt laminar process, notched 

 at middle. There is a circular fovea at middle of first ventral 

 segment. The female lacks this and also the prothoracic 

 process. ]?eneath both sexes have the oblique strigosity before 

 descril)ed. Fully developed males are 1-8 x 07 mm. in size. 

 Females and depauperate males are smaller. Twenty-four 

 .specimens. Cincinnati, Ohio, Mobile, A\a.^ and New Jersey. 



SULCACIS, n. gensus 



Small size bristling with erect setae. The epistoma has 

 the margin .subtruncate across its front, with a strong sul- 

 cation at its base, between the lower border of the eyes. The 

 apical margin of prothorax is rounded and simple in both sexes. 

 The maxillary palpi are large, elongate and bluntly pointed. 

 The i)rosternimi is broadly excavated in front and flat between 

 coxae. The antennae are 9-jointed. The anterior tibiae are 

 produced and everted at apex. The males have sexual marks on 

 first .segment. The structure of this genus recalls Plesiocis 

 Csy., but the antennal club lacks the large, sensitive pores filled 

 \\\[h white spongy pubescence. It is a rather feebly characterized 

 genus. I have seen two species in the above genus. They are:
