 JULY 7th, 1910. 



The sixty-fifth regular meeting- of the Society was held in 

 the usual place. 



ENTOMOLOGICAL PEOGKAM. 



Mr. Ehrhorn exhibited 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- 

 ported from Australia. Recently new forms have been reported 

 from other countries. One species OlUfiella cristicola from the 

 United States and at the February meeting I recorded a new 

 species, Cissococcus? oaliuensis, foimd on Opuhe (Urera sand- 

 irichensis) on Tantalus, Oahu. Mr. O. H. Swezey brought me 

 a semi-gall-forming coccid, a Pseudococcus 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. 



Many of the Galls made by coccids could be taken for seed- 

 pods, and the resemblance for instance of Cylin^drococcus 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 usualh^ prolonged and at times 

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

 ehai'ged. Some galls contain a single individual, Avhile 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 Apiomorpha duplex resembles the seedpod of Mar- 

 ti/nia prohocidea when the probocis-like hood is open." 



The talk Avas 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. 

 He had never seen galls made by scale insects before and agTeed 

 with the other members that they did resemble seedpods of 

 trees. One in particular made by Apiomorpha duplex resem- 

 bled the seedpod of the Mexican Martynia prohocidea after the 

 pods had opened. 



Mr. Ehrhorn also exhibited a pair of very rare Leucanid 

 beetles from 'New Guinea. 



Mr. Terry exhibited a fiy of the genus Dyscritomyia, which
