82 Mr. Babington on Dromius. 



This insect very much resembles D. ugilis, but may always be 

 distinguished from it by the characters given above. 



The thorax is rather broader than long, narrower behind, and 

 has the hinder angles less prominent. The elytra have only one 

 series of punctures upon the disk of each, i. e. on the 6th stria from 

 the suture. 



A variety is sometimes found at Cambridge with the centre of 

 each elytron ferruginous. 



This insect does not appear to be rare, but is generally confounded 

 with D. agiUs. A good many specimens have occurred at Cambridge, 

 and it is probably pretty generally distributed throughout this coun- 

 try.

Head black ; mouth, palpi, and antenna pale ferruginous ; thorax 

 quadrate, a good deal contracted behind, and the angles round- 

 ed, red ; elytra with the humeral angles rather prominent, 

 nearly rectangular, with the angular point rounded, brown, 

 having two pale spots on each ; one large oblong placed near 

 the base and extending nearly to the middle ; the other smaller 

 transverse, sometimes wholly covering the apex, at others 

 leaving a narrow dark line on the suture and external margin. 

 In some varieties the spots on the elytra join, and in others 

 the apical one is nearly or totally wanting. 

 Common under the bark of trees and in moss, but the varieties are 

 rai-e. 



4. D. quadrinotatus. Dej. 



Elongatus ; capite nigro ; thorace subquadrato, postice attenuate, 

 angulis posticis prominentibus ; elytris fuscis, maculis duabus, 

 antennis pedibusque pallidis ; subtus piceus. 



Long. 1-^ — 2, lat. ^ — 4 lin.
