294 THE CA.NADIAN ENTOMOLOGIST. 



Soaps. — Various soaps were also tried, and of these the Whale-oil 

 Soap Emulsion gave the best results, many of the scales being killed. 



The Whale-oil Soaj) gave good results also, but not equal to the 

 Emulsion. 



Sunlight and Lifebuoy soaps, and also a mixture of both, proved to 

 be of very little value, inasmuch as they did not prevent the eggs from 

 hatching. These soaps are claimed by the makers to be most effective 

 against the San Jose and other scale insects, but applied as a winter wash 

 against the Bark-louse they have little value. Undoubtedly they should 

 be applied after the young lice hatch, and not as a winter application, and 

 then would most likely prove effective against the tender lice. 



Kerosene Emulsion. — Kerosene Emulsion was also tried, and this 

 proved of more value than the Whale-oil Soap Emulsion, but not so 

 effective as the lime, salt and sulphur wash. 



Lime. — Quick slaked lime, ij^ lbs. to i gallon of water, proved very 

 effective applied as a winter wash, and equalled the results obtained by 

 the lime, salt and sulphur. 



Kerosene-Lime. — This was also tried, but did not prove superior to 

 the Kerosene Emulsion, and therefore is not to be preferred to it. 



A NEW CRYPTINE GENUS FROM CUBA. 



BY WILLIAM H. ASHMEAD, M.A., D.SC, WASHINGTON, D. C. 



Some years ago Mr. J. M. Espin, of Guantanamo, Cuba, sent to Dr. 

 L. O. Howard for names some parasitic Hymenoptera, among which I 

 indicated a new genus, but which I neglected to describe. As Mr. Espin 

 has recently written about it and desires its early description, I submit the 

 following : 



Nesolmoceras., new genus. 



Resembles Li?ioceras, Taschenberg, in the shape of the abdominal 

 petiole, which is straight or nearly, not elbowed, and only slightly 

 thickened at apex. It also resembles somewhat /oppidium, Walsh. In 

 my Classification of the Ichneumon Flies, 1906, p. 40, it will fall in next 

 to Walsh's genus on account of the metathoracic characters and the 

 transverse median nervure in the hind wings being broken above the 

 middle. 



The two, however, may be easily separated by the following 

 differences :
