Body deep black, much punctured : head short behind the 

 eyes, with distant punctures, more dense on the rostrum : an- 

 tcnnaa rufous: thorax with numerous [253] dense punctures: 

 scutel white : elytra slightly hairy, with punctured striae ; the 

 interstitial lines crenate : feet piceous : thighs with a slight angle 

 on the inferior middle : tarsi rufous. 



Length one-tenth of an inch. 



I obtained two specimens on the Kalmia latifolia in July. 

 It is a small species. 



[Is the type of Piazorhinus Schonh. — Leg.] 



APION Herbst. 



1. A. EOSTRUM. — Black ; thoracic punctures large, dense ; an 

 impressed line, and punctures between the eyes. 



Rht/nchites 7'ostru7n Melsh. Catal. 



Body entirely black : vertex impunctured : front with large 

 punctures, and a longitudinal impressed line ; an impressed lon- 

 gitudinal line between the antennae : thorax with large, concave, 

 close set punctures ; an impressed, abbreviated line on the mid- 

 dle of the posterior subnuirgin : elytra striate, the striae rather 

 wide, punctured, interstitial lines flat topped with a single series 

 of small hairs. 



Length from the tip of the rostrum less than three-twentieths 

 of an inch. 



This is a very abundant species. Dr. J. F. Melsheimer found 

 it on the leaves of the Rohrnia ])seufhtcan'a ; and Dr. Harris of 

 Milton, Massachusetts, informs me that it occurs in all its stages 

 in the seed vessels of the wild indigo, (^Bapfisia tinctoria,) in the 

 months of August and September. I have also taken it in 

 plenty on that plant. It seems to be allied to [254] the A. ni- 

 grum Herbst., but it does not agree with his figure, nor suffi- 

 ciently well with his description.
