Male. — Antenim hirsute, 10-articulate : basal joint longest, 

 cylindric ; 2nd and 3i-d joints longer that broad ; 4th rather 

 shorter than these ; 5th nearly twice the length of 4th ; 6th 

 shorter than the preceding one; 7th almost quadrate;' 8th 

 transverse ; 9th largest, nearly obconical, not exactly trun- 

 cate at apex, acuminate towards one side at the extremity; 

 10th almost rotundate, with a short, broad, tenuinal pro- 

 tuberance hollowed out underneath ; the two apical joints 

 asperate. Prostoiium somewhat granulated on the middle. 

 Anterior coxoi armed with elongate spines. Basal segment of 

 abdomen very large, bearing a pair of spiniform tubercles near 

 its extremity ; intermediate segments much reduced, almost 

 linear. 



Female. — Antennce similar in structure to those of the 

 other sex, except as follows : 11-jointed ; 9th joint considerably 

 larger than 8th, quadrate ; 10th nearly twice the breadth of 

 its predecessor ; 11th largest, subovate, obtusely prominent at 

 apex. 



In facies this species resembles Nos. 234, 235, and 1,G99. 

 B. dlsjxir is at once differentiated by the form of the terminal 

 joints (9 and 10)_of the antenna. In B. im2)ressifrons all but 

 the four basal joints of the antennae have a roughened aspect'; 

 and the protuberance of the penultimate articulation assumes 

 the form of a hook directed backw'ards ; and, moreover, the 

 sculpture of the head and thorax is altogether different. In 

 B. fraudulenta the last six antennal joints are rough -lookin,", 

 and, what is more characteristic, the head is angularl}- pro- 

 duced between the antenna3, and seems plane above when 

 view'ed in certain ways.

The species is dedicated to Mr. George Muuro, of Clevedon, 

 to whom I am indebted for seven specimens, as well as nume- 

 rous examples of other species of this interesting group. 



B. forficulida, n. sp. 



Elongate, convex, nitid; elytra and legs of a paler red than 

 the other parts of the body. 



_ AntenncB stout, not short, pubescent, 10-articulate : basal 

 joint rather larger than 2nd, and somewhat flattened above ; ■ 

 -3rd and 4th nearly equal, and bead-like ; 5th not so large as 

 2nd, yet larger than the preceding one; 6th shorter than 

 6th ; 7th and 8th quite transverse ; 9th large, subquadrate, 

 oblique at apex, foveate below ; 10th as broad as 9th, at least 

 one-third longer, obtusely pointed ; these two terminal joints 

 roughish. Head smooth, frontal foveai obsolete, the vertical 

 small but distinct. Thorax unimpressed, widest before the 

 middle. Elytra oblong, sutural striae finely marked; they 

 bear some minute brassy hairs. Hind-hody much narrowed
