This species was determined by me from a specimen taken 

 by myself at Wickham last April, and I have since detected 

 it in the collections of Mr. Waterhouse, Dr. Power, and 

 Mr. Douglas. 



It is closely allied to 3J. splendichis, but differs from that 

 insect as follows. It is apparently always larger, some- 

 what flatter and broader, the thorax especially being wider ; 

 the joints of the antennae are comparatively not quite so 

 stout, with the terminal joint more oblong ovate, and the 

 punctuation of the abdomen rather more remote. In colour 

 also it differs very considerably, being more uniform!}^ rufo- 

 testaceous, with only a slight scutellar patch and the base of 

 tlie abdominal segments (especially the fifth and sixth) more 

 or less pitchy ; whilst splendidus has the head and often the 

 greater portion of the elytra pitchy or even black, and the 

 abdomen more or less black, with the outer margins of the 

 segments testaceous. The head in longicornis is rufo-tesla- 

 ceous beneath, and black, with the gular area yellow^ in 

 splendidus ; in longicornis^ also, the three basal joints of the 

 antennae are especially lighter, whilst in splendidus the first 

 joint only is light. 



In the male of splendidus the sixth segment of the abdo- 

 men beneath is widely emarginate, the sides set with stiff 

 black hairs, and the emargination itself filled up with a very 

 thick bushy fringe of stout yellow hairs ; the seventh seg-
