236 APPENDIX. 



A very common species, particularly in July on the Ce- 

 anothus Americanus and other flowers. 



MELANDRYA, Fabr. Latr. 



1. M. striata. Black; thorax with three grooves; front 

 with an impressed dot ; elytra striate and punctured. 



Inhabits the middle and northern states. 



Serropalpus canaliculatus, Melsh. Catal. 



Head with numerous minute punctures; a distinct rather 

 longitudinally oval impressed spot between the superior 

 part of the eyes ; palpi at tip of the terminal joint, and one 

 or two terminal joints of the antennse dull rufous; thorax 

 gradually dilating to the base, from the width of the head 

 to that of the elytra; surface minutely punctured with small 

 sparse hairs; three dilated longitudinal grooves, or undu- 

 lations, obsolete before; lateral edge almost rectilinear to 

 near the posterior angles, where it is a little incurved, it is 

 vertically rounded before the middle, and acute behind the 

 middle ; posterior angles nearly right angled ; scutel sub- 

 orbicular, convex, punctured; elytra, stria? dilated, with 

 numerous punctures, those of the base being more distinct 

 as the strise are not so profound in that part. 



Length three-fifths of an inch. 



A specimen of this interesting insect occurred in the 

 North-west Territory. My friend, the Rev. John F. JVIel- 

 sheimer, with whom I corresponded on the subject of this 

 species, agrees with me perfectly in the jDropriety of placing 

 it in this genus, and in its being altogether different from 

 the S. canaliculatus, Illig. Melandrya canaliculatus, 

 Fabr. This conclusion indeed is irresistible, when we com- 

 pare our insect with the description of that of Europe, and
