1214 CiosO). Caepopiiilus coeticinus Erichs., Germ. Zeitscbr., lY, 1843, 



203. 

 Oral, slightly oblong. Piceous, feebly shining, minutely alutaceous, 

 sparsely pubescent ; legs and antennte dark reddish-brown. Thorax one- 

 half wider than long, as broad at apex as at base, sides feebly curved, hind 

 angles rectangular; surface, as well as that of elytra, rather densely but 

 not coarsely punctured. Prosternum densely and rather coarsely punc- 

 tured. Length 3 mm. 



Southern half of State; scarce. April -l-October 17. Resem- 

 bles a small niger but known by the form of thorax and more shin- 

 ing surface. Taken from beneath leaves of mullein and beaten 

 from flowers of linn. 



C. marguiatus Erichs.. length 1.5-2 mm., with sides of thorax 

 and elytra continuous, has been taken near Cincinnati. 



1215 (3681). Caepophilus braohyptbeus Say, Journ. Phil. Acad. Nat. 



Sei., V, 1825, 183 ; ibid. II, 288. 

 Oblong-oval, subdepressed. Piceous, very finely and sparsely pubes- 

 cent; legs and antennae reddish-brown. Thorax nearly twice as wide as 

 long, apex and base equal, sides moderately curved, punctures of the disk 

 rather coarse and not dense, those of sides finer and denser. Surface of 

 elytra more finely punctured than thorax. Prosternum nearly smooth. 

 Length 2.5 mm. 



Throughout the State; frequent, ilareh 20-October 17. Oc- 

 curs on flowers of cherry, apple, black haw and other shrubs and at 

 sap. Resembles the preceding, but distinguished by its smaller and 

 broader form and smooth prosternum. 



121C (3683). Caepophilus antiqxjtjs Melsh., Proc. Phil. Acad. Nat. Sci., 

 II, 1844, 105. 

 Oblong. Piceous, moderately shining ; base of elytra reddish-brown, 

 gradually passing to piceous. Thorax one-third wider than long, base and 

 apex equal, sides feebly curved, hind angles rectangular ; surface sparsely 

 punctured at middle, more finely and densely on sides. Surface of elytra 

 coarsely but sparsely punctate. Prosternum coarsely and rather densely 

 punc-tured on sides. Hind tibire of males suddenly dilated at apical half. 

 Length 2.5-3 mm. 



Southern half of State; common. Hibernates beneath mullein 

 and rubbish in fence corners. Taken by sifting in early spring; 

 also at sap. ^March 17-December 7.

The members of this genus are broadly oval or oblong, strongly 

 flattened and sparsely pubescent beetles, which live beneath bark 

 and feed upon sap. The males have the last ventral segment emar-
