impressed line which connects with transverse angulated one : elytra 

 dark-brown or black; very distinctly striate or grooved, a large indis- 

 tinct brownish spot at the base and another at the tips. Anterior 

 tibiae as in Pasimachus. Length three-tenths of an inch ; width but 

 slightly more than one-fourth the length. 



It is supposed that this species preys upon the plum curculio (Con- 

 otrachelus nenuphar. ) 



HARP ALUS CALIGINQ8US — Say. 



Anterior tibiae, with a notch on the inside near the tip, with one 

 spur at the tip, with another above the notch, but without the ex- 

 ternal tooth. Thorax about as broad as the elytra sub-quadrate, 

 slightly narrowed in front, and depressed in the region of the hind 

 angles which are acute. Black except the antennae, palpi, tarsi and 

 anterior coxae which are brown. Head smooth ; elytra with distinct 

 striae which are smooth, that is without punctures. 



Length about one inch ; width nearly one-third the length. 



Known to prey upon various cut-worms (species of Agrotis), and the 

 potato beetle. 



H. PENNSYLVANICUS — Deg. 



The general form, although much smaller, 

 is the same as that of the preceding species; 

 the form of the thorax and tibial characters 

 'are as in that species. The general color 

 black, the under surface being deep piceous, 

 antennae, feet and palpi paler. The thorax 

 is smooth on the central portion, with a me- 

 dian longitudinal impressed line, the regions 

 of the posterior angles depressed and punc- 

 tured, these angles rounded. Elytra striate, 

 111..1ARPA pknhsylvanicus. the striae or grooves being smooth, not punc- 

 tured, but there are punctures along the margin. Length about 

 three-fifths of an inch; width nearly one-third the length. 



This is a very common species, often found under stones, logs, etc., 

 and frequently enters the house at night when there is a light. Mr. 

 Walsh noticed a larva, which is supposed to be of this species, feed- 

 ing upon the larvae of the Plum Curculio. 



lebia graxdis. — Hentz. 



Size rather below medium : elytra truncate or cut oft' at the extrem- 

 ity, leaving the tip of the abdomen exposed ; anterior tibiae, with 

 the notch on the inner edge; claws distinctly pectinate ; abdomen 

 somewhat pedunculated ; thorax rounded on the sides and wider than 

 long, the posterior margin straight, with the angles somewhat obtuse, 

 but not rounded, narrower than the elytra ; elytra slightly widened 

 posteriorly, of a deep or dark blue color, distinctly striate and with- 

 out visible punctures. The thorax horny, yellow, smooth, with an 

 impressed longitudinal dorsal line. Head yellowish, but a little 

 darker than the thorax, the legs and breast also yellow. Length 

 about or slightly over two-fifths of an inch ; width of elytra a little 

 less than half the Length.
