156 MANDIBULATA. COLEOPTERA. 



tibiae with three large and two or three small teeth : antennae rusty-piceous ; 

 the basal joint sometimes blackish. 



Var. jS. With the space between the arch of the sutural striae thickly rugose- 

 punctate throughout, especially towards the base, which in var. a is smooth. 



In some examples the legs are black, with castaneous spines ; and others have 

 the apex of the elytra piceous. 



The impunctate anterior and lateral margins of the thorax at once point out 

 the distinctions of this species. 



Not very uncommon on some of the coasts of Britain. " On the 

 coast near Cley, Norfolk." — Rev.W.Kirby. "Swansea." — Dr. 

 Leach and L. W. Dillwyn, Esq. " Southend."— Rev. F. W. Hope. 



Sp. 28. semistriatus. Convexus, ater, obscurus, thoracis disco postico Iwvi, elytro- 

 rum basi impunctato, striis quinque abbreviatis, apice interno punctato, tibiis 

 anticis siibundulatis. (Long. corp. 1^ lin.) 



Hi. semistriatus mihi. 



Convex, black, obscure : forehead smooth, with a longitudinal impressed line : 

 thorax very finely punctured on the lateral and anterior margins, with a narrow 

 streak of punctures on the posterior edge, having a smooth patch on the hinder 

 portion of the disc : elytra each with an entire stria at the suture, curved at the 

 base and united to the second, which extends obliquely across to the middle 

 of the disc, and is followed by three other equidistant ones, of which the third 

 is longest, and the space between it and the preceding at the base is rugose ; 

 and on the shoulder is a short oblique stria closely approximating to the ad- 

 joining one; the apical half of the elytra, except a small patch at the outer 

 tip, is thickly and rather deeply punctate ; legs and antennae pitchy-black. 



This species may be known from the others of this division, by having the an- 

 terior half of the elytra impunctate, and adorned with four equidistant oblique 

 stria?, reaching to about the middle of the disc, with the space between the 

 third and fourth longitudinally rugose as in Hi. nitidulus, from which it differs 

 by its minute bulk, dissimilarity of form, &c. 



I possess a single example of this very distinct species, which I 

 obtained from Mr. Millard of Bristol, in the neighbourhood of which 

 city it was captured. 



Sp. 29. metallicus. Atro-violaceus,fronte rugosa, elytris apice interno punctatis, 

 extus striis quatuor abbreviatis, suturalique Integra, tibiis anticis quadri- 

 dentatis. (Long. corp. l\ lin.) 



Hi. metallicus. Fabricius.—Steph. Catal. 102. No. 1072. 



Deep violaceous-black, or greenish : the forehead with two transverse wrinkles : 

 thorax thickly rugose-punctate, with the disc posteriorly alone smooth, elytra 

 from the middle to the interior angle somewhat thickly punctate ; leaving the 

 anterior and outer limb smooth ; at the base are four oblique, short, stria-, 

 rather deeply punctate, and the inner one is connected to the second by a curved
