British Species of Homalota. 221 



finely punctured and delicately pubescent^ with the head, 

 abdomen, and sides of the elytra towards the hinder angles, 

 darker. The antennte are short and stout, considerably 

 thickened from the fourth to the seventh joint; joints 

 two and three very nearly of equal length, four small but 

 transverse, five considerably broader than four, it and the 

 following strongly transverse; eleventh joint pointed, as 

 long as the two preceding. The head is pitchy, con- 

 siderably narrower than the thorax, narrowed behind the 

 eyes, finely and indistinctly punctured. The thorax is 

 rather narrower than the elytra, its breadth about twice 

 its length, narrower at the anterior angles than at the 

 base, very finely and moderately closely punctured. The 

 elytra are about a third longer than the thorax, reddish, 

 infuscate towards the apical angles, finely and pretty 

 closely punctured. The abdomen is shining, pitchy-black, 

 obscurely paler at the base and apex ; segments two to 

 four finely and sparingly punctured, five and six nearly 

 smooth. Legs yellow. 



The male characters are very peculiar, but not easy to 

 describe. The seventh abdominal segment has the dor- 

 sal plate in the middle a little produced behind, and the 

 middle of its hind margin presents a shallow notch, the 

 margin of which is a little thickened ; a little before the 

 hind margin, and close to the outside, is to be seen on each 

 side a distinct raised tubercle ; moreover the lateral mar- 

 gin of this segment, is, on each side, produced behind, 

 into a very slender and very indistinct spine, not reaching 

 so far back as the produced middle part of the segment. 



Very rare. I have seen only a few specimens, all of 

 which have been taken by Dr. Power, in the neighbour- 

 hood of London.
