152 MANDIBULATA. — COLEOPTERA. 



Sp. 19. purpurasceus. Ater nitidus, convexus, elytris externe quinque-striatis, 

 disco ruhris, tihiis anticis quinque dentatis, dente extimo integro. (Long, 

 corp. 2 lin.) 



Hi. purpurasceus. Fabricius.—Steph. Catal. 101. No. 1061. 



Convex, shining black : thorax with a deep lateral line extending to the base, 

 and rather close to the margin : elytra subconvex, with a more or less distinct 

 undefined red spot or patch on the disc, sometimes, though rarely, obliterated ; 

 and each with five entire striae, and two inner abbreviated ones : legs and 

 antennae piceous ; anterior tibiae with five teeth, the outer ones simple. 



The red patch sometimes occupies nearly the entire disc of the elytra, and the 

 insect is not unfrequently of a more or less intense castaneous-brown. 



Exclusively of the red disc of the elytra, this species may be known by its short, 

 convex form, by the five- toothed anterior tibiae, the outer of which is simple, 

 by the dissimilar position of the striae on the elytra, and the integrity of the 

 lateral line on the thorax. 



Common in the neighbourhood of the metropolis : in profusion 

 at South Lambeth in April last ; and frequently observed in other 

 parts of the country. " Netley, Deal, and Southend." — Rev. 

 F. W. Hope. " Not common (near Swansea)." — L. W. Dittwyn, 

 Esq. " Carlisle." — T. C. Hei/sham, Esq. 



Sp. 20. castanipes. Ater, subnilidus, paulo convexus, elytris externe quinque- 

 striatis, pedibus piceo-castaneis, tibiis anticis undulatis. (Long. corp. 2 lin.) 

 Hi. castanipes. Kirhy MSS.—Steph. Catal. 101. iVo. 10G3. 



Black, slightly glossy, and a little convex : thorax with the lateral line extending 

 to the base, where it is slightly rounded : elytra rather convex, with five an- 

 terior simple striae externally, one parallel with and close to the suture, about 

 two-thirds the length of the elytra, and between it and the outer ones a very 

 faint short one, scarcely a third of the length of the former : legs pitchy cas- 

 taneous ; the anterior tibiae undulated externally : antennae ferruginous. 



From the former this species differs in having the upper surface entirely black, 

 and the inner striae on the elytra of very dissimilar length, the anterior tibiae 

 waved exteriorly, and the legs castaneous. 



Taken near London and in Suffolk, but not common. 



Sp. 21. caliginosus. Suboblongus, ater nitidus, elytris striis tribus integris, 

 tribus abbreviates, tibiis anticis quinque-dentatis, dente extimo bifida, anten- 

 narum clavd ferruginea. (Long. corp. 2^ lin.) 



Hi. caliginosus. Steph. Catal. 101. No. 1065. 



Rather oblong, deep, very glossy black : thorax with the marginal line rather 

 deep, punctate, and with an abbreviated bent, one on the anterior angle, as
