ment is more deeply, but not so widely, emargiuate, the 

 emargi nation having its sides also thickly fringed with stout 

 yellow hairs, and terminating at its upper and smaller end 

 in a thick button of similar golden pubescence, the whole 

 forming a very stout semi-erect cushion, slightly curved to- 

 wards the apex of the abdomen. 



In J\J, longicornls (male) the sixth segment is very gently 

 emarginate, the sides set with .stiff black hairs, and the 

 emargination fringed with very short fine yellow pubescence, 

 whilst the seventh segment is not so decidedly emarginate as 

 in M. sple/ididuSj the emargination being edged with short 

 sligiit yellow hairs, and terminating at each outer angle in 

 a pencil of long golden pubescence, the flat part of the under 

 surface of the seo^ment beinj^ clothed with verv short, fine 

 yellow down. 



The unvaryinf]^ size of one line o'iven bv Kraatz for 

 31. splendidus is erroneous ; I have seen specimens of that 

 species sent over by Kraatz himself, for which the smallest 

 length should be a line and a half.

 The insect for which Thomson has proposed the name 

 succicola, hitherto known as P. carbonarius, Gyll., appears 

 to differ from the latter species in having a lesser head, the 

 thorax punctured on the sides, the penultimate joint of the 

 antennae transverse (in carbonarius, Gyll., it is not so broad 

 as long), and the sixth segment of the abdomen beneath, in 

 the male, widely and gently emarginate, in addition to the
