a little darker above, tlie upper notch wide, rounded triangular, reaching from 

 side to side of the segment, and extending cephalad almost to the hind margin 

 of tlie last dorsal segment, the lower notch angular, with straight sides, and a 

 small, almost semicircular, excavation in the middle ; viewed from the side the 

 hind margin passes obliquely and almost in a straiglit line from the hind 

 margin of tlie last dorsal segment to tlie commencement of the lower notch. 

 Contents of the genital aperture brownish-yellow. Anal tube with the aperture 

 transversely elliptic, its lower edge much widened and produced on each side 

 into a large, blunt, triangular tootli, the teeth proper nearly straight and 

 directed almost horizontally cephalad. Genital apertiu-e (or mouth of the 

 pygofer) somewhat triangular, with widely rounded angles. Styles gradually 

 narrowed from base to apex, nearly straiglit, their apices obliquely truncate, 

 with tlie upper and lower angles produced into a sharp triangular tooth. 

 Scutellura with a black sub-triangular patch on each side beyond the side keels. 

 Otherwise like G. glaucescens." 



? . Brachypterous form. Bright green, and without a trace of the dark 

 ti'iangles on scutellum wliich characterize the ^ . Much like C. glaucescens ? , 

 but with face liroader between the keels, and with the liind margin of the 

 terminal segment of the abdomen always black, this dark I'im 1»eing sometimes 

 interrupted in the middle of the upper surface. Occasionally there is a broad 

 but ill-defined fuscous band just within the hind margin of each dorsal abdo- 

 minal segment, and two or three dark dots on the sides of each. Length, 4 mm. 

 Mucropteronsfortn. Scutellum rather more than twice as long as prono- 

 tum, yellowish, with dark triangles indicated, though not so distinct as in the

Ischnomera sanyuimcollis, F., and other beetles in the New Forest. — At the 

 beginning of June I had a few days' collecting in the New Forest; the 

 weather, however, was wet and cold for nearly the whole time, and only one 

 day could have been characterised as really favourable. I managed, however, 

 to beat a small series of Ischnomera sanguinicollis off the more or less be- 

 di-aggled hawthorn bloom ; probably during tlie preceding week, which was 

 hot and fine, it had been fairly abundant in the locality ; I. coerulea was common, 

 as also was Corymhites tessellatus, and Grammoptera prseusta, but the latter was 

 very local ; under bark of an old, wet, decaying stump I found two pup® of 

 Athous rhomheus, from which I iifterwards bred the perfect beetles ; among 

 other things may be mentioned single specimens of Elater lythropterus,
