E.M.M. as V. reitteri, and for comparison a specimen of 

 1^1 bolivari, Rtt. These two are the only dark-coloured 

 species of the genus at present known. In both cases the 9 ? 

 are unknown, but are probably only furnished with rudimentary 

 wings as is usual in this genus. 



Hybrid Oporabias. — Mr. E. A. Cockayne exhibited the 

 following specimens of this genus : 0. cJunstyi from Ix'eland 

 and Scotland, hybrid 0. christyi ^ x 0. dilutata $, and 0. 

 dilutata $ x 0. christiji $; 0. dihitata from Scotland and 

 Epping Forest, hybrid 0. dilutata $ x 0. atitumnaria $, and 

 larva ; 0. autumnaria, hybrid 0. autumnarm $ x 0. filigram- 

 maria 9, and 0. fillgranimaria ^ x 0. autumnaria $ ; 0. 

 filigrammaria from Yorkshire and Scotland. Most of the 

 hybrids were bred by Mr. J, E. R. Allen. He remarked that 

 the species fall naturally into two groups — 



(1) 0. dilutata and 0. christyi. 



(2) 0. aittumnaria and 0. filigrammaria, 



and that hybridisation is easy between the members of each 

 group, but very difficult between the members of the different 

 groiips, though probably all are good species. The hybrid 

 dilutata and autumnaria showed the dull grey of dilutata, a 

 colour never met with in autumnaria whose melanic forms 

 are brown, but has the markings of the latter, the sharp 

 angle in the elbowed line and the central spot far from the 

 line.
