128 SERRICORNIA. [Pyroptenu. 



has described another from Borneo ; it may be easily known from tho 

 preceding by the sculpture of the interstices of the elytra, and the small 

 third joint of the antennas. 



P. affinia, Payk. Smaller and more parallel-sided than Eros 

 Aurora, which it strongly resembles in general appearance ; it may, 

 however, be easily known by its black thorax, which, like E. Aurora, is 

 furnished with five areolets, and by the shorter transverse third joint 

 of the antennae, and especially by the fact that the interstices between 

 the costae of the elytra are furnished with a single and not a double row 

 of cells; the elytra are dull, but the scarlet colour is very bright. 

 L. 6-7 mm. 



Male with the antennae longer, and the seventh ventral segment of 

 abdomen semicircularly emarginate at apex. 



Female with the antennae shorter, and the seventh ventral segment of 

 abdomen subtruncate at apex. 



Extremely local ; Mr. Rye first introduced the species on a single specimen taken 

 at Killarney by a son of Mr. J. Hardy in 1866 ; it WHS subsequently taken in some 

 numbers by the Rt-v. A. Matthews and his brother in Sherwood Forest ; it occurred 

 on one of the hottest days of summer, flying over and settling on bracken in one 

 -articular spot, in which Mr. Matthews took a large series. 



PLATYCIS, Thomson. 



This genus contains three European species, and Mr. Gorham has 

 joined to it P. nasafus from Japan; the produced forehead and the 

 indistinct sculpture of the interstices of the elytra, which are obscurely 

 biseriately areolate, will at once distinguish it. 



P. minutus, F. (jmsilla, Gmel. ; <$ nigrorubra, DeG.). Black, with 

 the elytra scarlet, the colour not being quite as bright as in Pyropterus 

 affinis, to which species it is closely related ; it may be at once known 

 by having the forehead strongly produced between the antennae, which 

 are not contiguous, and have the last joint testaceous yellow or reddish- 

 yellow, and the third joint much longer than second ; the thorax has 

 three areolets in front and two lateral ones behind, opening into a 

 central areolet ; the elytra are thickly clothed with reddish-yellow 

 pubescence, and are furnished with four costae, which are not so pro- 

 nounced as in the allied genera, the interstices being filled with an 

 indistinct double row of small areolets; legs black or fuscous, claws 

 reddish. L. 4-5| mm. 



Male with the antennae longer, and the seventh ventral segment 

 deeply excised at apex. 



Female with the antennae shorter, and the seventh ventral segment 

 subtruncate at apex. 



In old stumps of fir, Ac.; occasionally by sweeping and on the wing; very local; 

 Stephens records it as found on oak at Cooinbc and Birch Woods in August and
