24 MANDIBULATA. — COLEOPTERA. 



The deep colour of the elytra of this species, with their rufous tip, at once points 



out its distinction from its congeners. 



I possess a pair of this insect, captured by myself near London 

 many years since. 



B. ^Vith the thorax tuberculated, the anterior margin elevated or reflexed. 



a. Thighs unarmed. 



Sp. 8. Geranii. Niger, suhtus albido-squamosus, thorace obsolete bitubercuiato' 



untice transversim impresso, elytris striatis, interstitiis seriatim tuberculatis.

 Cu. Geranii. PaykuL—Ceu. Geranii. Steph. Catal. 152. No. 1535. 



Black, beneath densely clothed with white scales : the thorax obsoletely bituber- 

 culated, with a transverse impression in front : the elytra striated, the striae 

 obsoletely punctate ; the interstices each with a row of elevated squamous 

 tubercles : legs black ; tibiw with an obtuse tooth exteriorly towards the apex : 

 Jhnorn simple. 



The tuberculated interstices of the elytra, and the obtuse tooth near the apex of 

 the tibiae, and unarmed femora, suiRciently characterize this species. 



Not common near London : I have taken it in Darenth-wood 

 and at Ripley : found in Norfolk and in Devonshire. " Among 

 herbage on Crwmlyn-b arrows, and by Mr. Millard in clover." — 

 L. W. Dillwijn, Esq. " Scotland."— 2?gt'. W. Little. 



b. With the femora dentate. 



Sp. 9. didymus. Convexus, niger, subtus albo-sqiiamosus, thorace canaliculato, 

 bituberculato, elytris profunde punctato-st?-iatis, maculis quatuor albido-squa- 

 mosis. (Long. Corp. 1 1 — if Hn.) 



Cu. didymus. Paykul.—Ceu. didymus. Steph. Catal. 152. No. 1536. 



Convex, black; clothed with white scales beneath; thorax thickly punctate, 

 with a dorsal groove, and a short tubercle on each side, the sides rather densely 

 squamous : elytra deeply punctate-striate, jvith four whitish squamous spots, 

 which are very readily abraded, one in the middle and another at the apex of 

 each elytron: tibios and tarsi ferruginous ; antennae ferruginous, with the 

 club dusky. 



The four-spotted elytra, ferruginous tibiae and tarsi, and dusky club of the 

 antennae, are the chief diagnostics of this insect. 



Found abundantly in hedges near London, and I believe in other 

 parts ; certainly in Norfolk and in Devonshire. " Common in the 

 woods at Penllergare." — L. W. Dillwyn^ Esq. 



Sp. 10. Urticae. Subconvexus, niger, suhtus cinereo-squamosus ; thoi-ace im- 

 punctato, lined media exarato, elytris profunde striatis. (Long. corp. 1^ — 1^ 

 lin.)
