half the length of body, the club loosely three-jointed. Head coarsely and 

 rather closely punctured. Thorax one-half wider than long, sides feebly 

 curved, margins rather wide and distinctly reflexed ; front angles rather 

 prominent, hind ones obtuse ; disk convex, rather closely and coarsely punc- 

 tate. Elytra a little wider at base than thorax, feebly narrowed from mid- 

 dle to the rounded tips ; each with numerous closely placed rows of rather 

 coarse slightly impressed punctures. Length 3 mm. 



Marion and Hancock counteis; frequent. April 6-October 15. 

 Taken by Harold Morrison from a cellar in which wood had been 

 stored. Resembles Typhoe fumaia L., but more coarsely punctate 

 and less pubescent.

In this genus and the next two the thorax, has two small, deep 

 and widely separated foveas or pits near the basal margin. The 

 genus is represented by the single species : 



1089 (3355). Texmatopiiilus amertcanus Lee, N. Sp. N. Amer. Col., I, 



1863, 70. 



Elongate-oval, convex. Dark reddish-brown to piceous, rather shining, 

 the pubescence yellowish to ashy gray ; antennas and legs reddish-brown, 

 the former scarcely as long as head and thorax. Thorax a third wider 

 than long, finely and densely punctate, sides evenly curved, the edges very 

 finely serrulate; apical angles obtusely rounded, hind angles acute. Elytra 

 slightly wider than thorax, the punctures much less dense. Length 2.5- 

 3 mm. 



Northern half of State ; locally common on the flowers and leaves 

 of the semi- aquatic plant, arrow-arum, Peltanclra virginica L. May 

 20-June 25. 



IV. Loberus Lec. 1861. 



Small oblong species resembling, at first sight, certain " flea- 

 beetles ' ' of the family Chrysomelidse. From the members of allied 

 genera they may be most readily known by the elytral punctures 

 being arranged in rows, and bearing very short, fine, recurved hairs. 

 One of the five known species occurs in Indiana. 



1090 (3356). Loberus impresses Lec, N. Sp. N. Amer. Col., I, 1803, 70. 

 Elongate-oval, convex. Dark reddish-brown to blackish, shining ; sparsely 



pubescent. Antenna) slightly longer than head and thorax, paler than body. 

 Thorax narrower than elytra, nearly twice as wide as long; sides feebly 

 curved, disk sparsely and rather coarsely punctate, basal depression broadly 

 impressed. Elytra three and a half times as long as thorax, the apex 

 rather narrowly rounded; intervals smooth and without punctures. Length 

 2-2.3 mm.
