 lated, with an indented oblique line above ; punctures dilated : 

 scutel rounded at tip, base punctured, tip impunctured : elytra

ENGIS Fabr. 



1. E. CONFLUENTA [coNFLUENs]. — Black; elytra testaceous, 

 apex and about three spots on each black ; margin black. 



Inhabits Missouri. 



Head, thorax and scutel black, punctured ; elytra yellowish or 

 testaceous; apex black; exterior edge undulated with black; a 

 common line at base about [196] one half the length of the 

 suture, with a small lateral spot ; humerus, and larger spot on the 

 middle of each elytron communicating with the margin, black. 



Length more than one-fifth of an inch. 



This species was found by Mr. Thomas Nuttall. 



[A species of Ips, afterwards described as I. Dejeanii Kirby,

2. E. heros. — Black ; elytra bifasciate with rufous, the ante- 

 rior band with an angular black spot. 



Length three-fourths of an inch. 



Body black ; thorax slightly punctured at the anterior angles, 

 and with dilated confluent punctures in the indented basal lines: 

 elytra impunctured with two broad rufous undulated bands, in- 

 terrupted at the suture ; basal band broadest, with an angular 

 black spot near the humerus, and a common transversely oblong- 

 quadrate black spot behind the scutel. 



It occurs on the Missouri, and is a fine insect, probably one 

 of the largest of the genus. In the colors and form of body it 

 most strikingly resembles ^./ascia^a Fabr., but it is much larger, 

 and there is not the slightest oppearance of punctures on the 

 elytra ; the humeral black spot is angular, and its anterior angle 

 is extended towards the humeral angle ; the basal portion of the
