70 SEHKICOKNIA. 



shining, punctured, with three white spots on each side of abdomen; 

 legs more or less metallic. L. 8-12 mm. 



Male with the anterior tibiro terminating in a small hook on their 

 inner side. 



Found flying about old oak stumps, and settling on tliera ; the larva is fund in 

 the bark of oak stumps in fresh clearings iu woods; very local; Durenth Wood 

 (where it bas been taken in numbers by Dr. Power, and also by Mr. Champion) ; 

 Hampsteud and Cucktield (Stephens). 



A. sinuatus, 01. (chryseis, Curt.). Of a coppery-red or purplish 

 colour, dull, under-side bronze-green; very closely allied to the pre- 

 ceding, but with the elytra more closely sculptured and more evidently 

 granulate, and almost always without a white spot before apex; the 

 abdomen, moreover, is without the white spots at the sides, and the 

 front margin of the prosternum is deeply and triangularly emarginate; 

 the last segment of the abdomen is entire; the average size is smaller 

 than in A. ligutlatus. L. 7-8 mm. 



On low thorn bushes ; very rare; near Brockenhurst, July and August (Turner, 

 Matthews, and others) ; near Windsor and London (Stepheus). 



A laticornis, 111. (laticollis, Kies.). Elongate, narrow, gradually 

 contracted behind, somewhat depressed on disc, of an olivaceous green 

 colour; head rather strongly and rugosely punctured, forehead flat, 

 vertex of head obsoletely furrowed, antenna? as long as head and thorax, 

 very strongly widened in the middle in the male; female with the 

 antennae thinner than in the male, but still somewhat dilated; thorax 

 transverse, somewhat widened in front, coarsely and rugosely punctured, 

 more or less strongly impressed at base; scutellnm with engraved trans- 

 verse line; elytra long and narrow, granulate, narrowed at apex; legs 

 dark metallic. L. 4-5 mm. 



Besides the difference in the antennae, the male has the last segment 

 of the abdomen longitudinally impressed in middle, and the anterior 

 tibiae sinuate towards apex and terminating in a small hook. 



By beating young hazels, oak, birch, &c. ; local, but not uncommon where it 

 occurs; Dari/nth Wood, Leith Hill, Coombe Wood, Shirley, Ashtead, Balcombe, 

 Tonbridge, &c. ; Portsmouth district ; New Forest ; Bewdley Forest ; Buddon Wood, 

 Leicestershire; Hopwas Wood, Tainworth ; Robins Wood, Kepton ; York. 



A. ang-uBtuluB, 111. (olivaceus, Gyll.). Very closely allied to the 

 preceding, but distinguished by the antennae not being dilated in male, 

 and by the fact that the second abdominal segment in the same sex has 

 two small prominences in the middle of apex; these, however, are 

 occasionally obsolete, and cannot always be regarded as a reliable 

 character; in the female the sutural angle is simple, whereas in A. 

 laticornis it is slightly produced; in general shape and structure the 

 species so closely resembles the preceding that it does not require a 

 separate description. L. 3^-5 mm.
