British Species of the Genus Gyrophana. 245 



and thorax are alutaceous. The elytra (if we except a largish 

 patch of pitchy black at the outer apical angle) are paler than 

 other parts, and present distinct, and rather widely separated 

 punctures. The abdomen is for the most part pitchy, but paler 

 at the base and extreme apex, and also on the edges of the inter- 

 mediate segments. 



I have taken this insect in fungus, in the London district, and 

 in Windsor Forest and the New Forest. It is by no means un- 

 common.

Testaceous; head, outer posterior angles of elytra, and penulti- 

 mate segments of abdomen piceous ; thorax rufo-piceous : head 

 with a few scattered punctures ; the disc raised : antennae with 

 the intermediate joints but little dilated and but little broader than 

 long : thorax with two longitudinal discoidal depressions, and with 

 a row of punctures in each depression, of which one, near the 

 anterior margin, is moderately distinct, and one on the posterior 

 3rd is large and strong ; the rest obsolete : elytra smooth. 



Male with two very minute tubercles at the apex of the 6th 

 abdominal segment ; the 7th segment larger than usual, gradually 

 contracted in width towards the apex, and with a smallish tri- 

 angular emargination at the apex. 



The average size of this insect is rather less than in G. nana, 

 and a little larger than in G.fascinta. The head and thorax are 

 alutaceous, and the punctures are less distinct than in G. nana; 

 the intermediate joints of the antennae are less dilated, and less 

 transverse, and the elytra are almost perfectly smooth. The 

 thorax is boldly rounded behind, and but moderately rounded at 

 the sides ; the anterior angles are obtuse. In the male, tubercles 

 corresponding' with the outer pairs on the 6th abdominal segment 

 in G.fasciala are traceable, but they are very indistinct. 



I possess specimens of this species from Mr. Heysham's col- 

 lection, and Mr. Brewer has furnished me with others which form 

 part of a considerable series taken by him in fungi at Reigate. 

 Dr. Power has met with the insect, also in fungi, at Guernley, 

 Leicestershire, and at the Holt Forest, Hampshire ; and Mr. Rye 

 has taken it at Coomb Wood.
