basal four joints of the club are wider than long, the basal joint longer than the 

 others compared with the vridth, the last is longer and conical. Smooth and 

 shining. Parapsidal furrows distinct a transverse furrow at the base of the 

 scutellum, which at the base, bears two longish oval foveas. Post-scutellar spine 

 prominent, its base roundly curved, the apex curved at the top, the rest with 

 a longish straight, oblique, slope, which extends to near the apex of the meta- 

 notum. Abdominal petiole more than twice longer than wide, a stout keel 

 oa either side of the top and another down the sides. The lovver part of the 

 pro- and mesopleuras is bordered -by a stout keel ; down the middle of the 

 metapleuras are two curved keels, the two united by striae ; below and above 

 them is a more irregular keel. The legs-bear erect white hairs, the hind

END OF HYMENOPTERA. 



(Since the last instalment of the Hymenoptera was published we have 

 received the news of Mr. Cameron's sudden death at New Mills, Derbyshire, 

 on the 1st December, 1912. His age was 65 and for forty years he has been 

 known as a specialist in Hymenoptera. His earliest descriptions of new 

 species were published in the Transactions of the London Entomological 

 Society in 1876 and following years. Mr. W. F. Kirby in his list of Hymen- 

 optera in the British Museum, Vol. 1, 1882, said :— 



" I have to thank Mr. P. Cameron, of Glasgow, for types of several of 

 his new species of Tenthredopsis." 



In 1882 he commenced the publication of a work in four volumes, entitled 

 " British Phytophagous Hymenoptera." This was issued by the Ray Society 

 and is an authority for the class of insects dealt with. This was followed 

 by the Hymenoptera section of the Biologia Oentrali- Americana. The fact 

 that he was selected as one of the specialists on this monumental work proves 

 that his reputation in Hymenoptera was very high. 



Of late years he was known throughout the world. His willingness 

 to help was so conspicuous that many Museums and travelers sent him their 

 collections. In a bibliography of Hymenoptera for the two years 1906-7 he 

 is credited with thirty papers in journals published in England, Scotland, 

 Germany, United States, South Africa and Ceylon. Every specialist took 

 account of his work and it is interesting to note that Prof. Chester Bradley, 

 of Cornell University, connected his name with an Evanidla, collected at 

 Bartica by Mr. R. J. Crew. E. Cameroni was one of several new species 

 described in a paper entitled " The Evaniidse " published in the Transactions 

 of the American Entomological Society, June, 1908. 



By connecting the name of the late Rev. W. Harper with one of our new 

 species he brings to mind the fact that Mr. Harper contributed to " Timehri " 

 in 1888 a paper on The Beetles of British Guiana ; he also wrote on Lepi- 

 doptera for the " Argosy.")
