40 MANDIBULATA. COLEOPTERA. 



acuminated ; each elytron with ten striae, composed of deeply-excavated spots, 

 diminishing in size at the apex, the interstices impunctate : body testaceous 

 beneath; the femoral laminae deeply punctate: legs elongate, entirely tes- 

 taceous. 



Var. p. Steph. Catal. 1. c. — The punctures on the thorax and elytra larger than 

 in var. a ; the suture with a dusky spot in the centre. 



Var. y. Steph. Catal. 1. c. — The head dusky cinereous, the mouth pitchy. 



Var. I. Steph. Catal. 1. c— The head rufo- ferruginous : the elytra immaculate. 



Not very abundant near London : found occasionally in ponds 

 and ditches in Battersea-flelds, and near Hertford : also found in 

 Norfolk. " Putney and Wandsworth Commons." — Mr. Ingpen. 

 " In the pond in the Botanic Garden, Cambridge." — Rev. L. 

 Jenyns. 



Sp. 3. mucronatus. Plate XI. f. 1. — Rufo-ferrugineus, nitidus, elytris tenue 

 punctato-striatis, interstitiis Icevigatis, apice mucronato. (Long. corp. 2 — -2^ 

 lin.) 



Ha. mucronatus. Leach, MS S.— Steph. Catal. p. 43. No. 415. 



Ovate-acuminate ; deep rufo-ferruginous ; glossy ; head slightly punctulate : 

 thorax finely and very thickly punctulate throughout, especially on the hinder 

 margin : elytra faintly punctate-striated, the interstices impunctate, the apex 

 mucronated ; the disc convex, immaculate : body beneath pale testaceous-red ; 

 the ventral laminae deeply and coarsely punctate : legs and antennae ferruginous. 

 Distinguished from the following by the absence of punctations between the 

 striae, the mucro at the apex of the elytra, deeper colour, and totally punctate 

 thorax. 



My specimens of this insect were obtained from the neighbour- 

 hood of Swansea : I believe the Ha. ophthalmicus of Mr. Kirby^ 

 MSS. is synonymous; if so, it inhabits the county of Suffolk also. 

 " A single specimen taken at JBottisham." — Rev. L. Jenyns. 



Sp. 4. ferrugineus. Rufo-ferrugineus, nitidus, elytris profunde punctato-striatis, 



interstitiis seriebus punctorum minorum. (Long. corp. 2 — 2^ lin.) 

 Dy. ferrugineus. Linne. — Ha. ferrugineus. Steph. Catal. p. 43. No. 416. 



Ovate acuminate, glossy, ferruginous-red : head finely punctate : thorax ferru- 

 ginous, with the disc rather smooth, the margins thickly punctate, the base 

 with a transverse streak of impressed dots : elytra ovate, much dilated at the 

 base, the apex obliquely truncate, rather acuminate, each with ten regular 

 punctate striae, the interstices with a faint row of small remote impressions 

 on each, and a continuous stria of minute approximating dots towards the 

 sutural stria: body deep glossy ferruginous beneath; the central laminae 

 paler, deeply punctate ; legs ferruginous. 



Var. /3. Steph. Catal. 1. c. — With the striae dusky, with a few oblong dusky- 

 black spots between. 



Var. y. Steph. Catal. 1. c. — The elytra dusky, thickly spotted with black in the 

 interstices between the striae.
