 JULY Ttk, 1010. 



The sixty-lifth regular meeting' of the Society was hehl in 

 the usual place. 



ENTOMOLOGICAL PKOGEAM. 



^\v. Ehrhorn exhihited a collection of remarkable galls made 

 by scale insects and made the following remarks: 



"Until a few years ago Gall-making coccids were only re- 

 })orted from Australia. Recently new forms have been reporteil 

 from other countries. One species OlUfiella cristicola from the 

 United States and at the February meeting I recorded a new 

 species, Cissococciis? oaJiueiisis. found on Opuhe (Urcra sarid- 

 iricltcnsis) on Tantalus, Oaliu. ]\[r. O. H. Swezey brought me 

 a semi-gall-forming coccid, a Pseudococciis species, probably new, 

 which he found on Sandalwood. From outward appearance of 

 this gall one would take it for that of a Psyllid, but it is a true 

 Pseudococcus. 



]\rany of the Galls made by coccids could be taken for seed- 

 pods, and the resemblance for instance of Cylinidrococcus spini- 

 ferous to the young seedpods of Ironwood, Casuarina, is indeed 

 very striking. Most of the gall-forming coccids belong to the 

 subfamily Dactylopiinae, and their structure is at times strik- 

 ingly specialized, the abdomen is usually prolonged and at times 

 ends in a peculiar tube, through which the honeydew is dis- 

 charged. Some galls contain a single individual, while others 

 consist of colonies, containing many individuals, each owning its 

 own gall, the whole forming a very striking gall. The galls of 

 the male coccids are usually smaller than those of the females. 

 The gall of ApiomorpJia duplex resembles the seed]iod of Mar- 

 ty )}ia prohocidea when the j)robocis-like hood is o])en." 



The talk was a very interesting one and Chairman Terry 

 thought that Dr. Lyon ,the H. S. P. A. Pathologist, would be 

 interested in them, so he excused himself and called Dr. Lyon. 

 Lie had never seen galls made by scale insects before and agreed 

 with the other members that they did resemble seedpods of 

 trees. One in particular made by Apiomorpha duplex resem- 

 bled the seedpod of the ]\rexican Jrarfijiiia prohoridea after the 

 })ods had opened. 



Mr. Ehrhorn also exhibited a pair of very rare Leueanid 

 beetles from 'New Guinea. 



Mr. Terry exhibited a fly of the genus Di/scrilorii i/ld. \vhi;'h
