128 SERRICORNIA. [Pyropterus. 
has described another from. Borneo ; it may be easily known from. the 
preceding by the sculpture of the interstices of the elytra, and the small 
third joint of the antenne. 
P. affinis, Payk. Smaller and more parallel-sided than Lros 
Aurora, which it strongly resembles in general appearance; it may, 
however, be easily known by its black thorax, which, like H. Aurora, is 
furnished with five areolets, and by the shorter transverse third joint 
of the antenne, and especially by the fact that the interstices between 
the coste 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 antenne longer, and the seventh ventral segment of 
abdomen semicircularly emarginate at apex. 
Female with the antenne 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 was subsequently taken in some 
numbers by the Rev. 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 
particular 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. nasatus 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. (pusil//a, Gmel. ; f'nigrorubra, DeG.). Black, with 
the elytra searlet, 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 antenne, 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 cost, 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. 45-53 mm. 
Male with the antenne longer, and the seventh ventral segment 
deeply excised at apex. 
Female with the antenne shorter, and the seventh ventral segment 
subtruncate at apex. 
In old stumps of fir, &c.; occasionally by sweeping and on the wing; very local; 
Stephens records it as found on oak at Coombe and Birch Woods in August and
