Entomological Society of Washington, Nov. 6, 1890. — Mr. Erwin 

 F. Smith was elected a member of the Society. 



Mr. Schwarz exhibited a larva of the genus Carabus with deformed 

 maxillary palpi. The right palpus is normally formed, except that the 

 suture between the first and second joints is nearly obliterated; the left 

 palpus is only 3-jointed, with the joints nearly transverse, as in Calosonia. 



Mr. Marlatt exhibited three female specimens of a species of the Trj- 

 phonid genus Metopius. The strikingly large and peculiar ovipositor of 

 this species w-as described, and reference was made to the literature re- 

 lating to this genus, from which it appears that the female has never been 

 properly characterized, if indeed it has ever been described at all. 



Dr. Marx gave some additional notes on his experiments with the bite 

 of Lathrodecius, but stated that the results had been wholly negative. 



Mr. Howard read a paper entitled, "The Habits of Pachyneuron," in 

 which he referred to the breeding records of this genus of Chalcididae, 

 recording twenty distinct rearings in North America, and made a number 

 of interesting deductions therefrom. 



Mr. Schwarz read a paper on the food habits of Corthylus piinctatissinius. 

 This Scolytid, previously known to infest the subterranean part of the 

 stems of Sugar Maple saplings, was found in large numbers in the roots 

 and subterranean stems of the common huckleberry, Gaylussacia resinosa , 

 in the vicinity of Washington during September and October. In this 

 connection Mr. Schwarz presented the description of a second North 

 American Corthylus, C. spinifer, from semi-tropical Florida. 



Mr. Marlatt presented a paper on the Final Molting of Tenthredinid 

 Larvae, in which he described the molting undergone by the larva of nearly 

 all saw-flies after full growth is reached and just prior to spinning up or 

 entering the ground to pupate, describing also the accompanying change 

 of color. Reference was made to the scanty literature of the subject and 

 the explanation of this molt by Cameron on the ground of protection. 



Mr. Townsend read a paper on the Leptid (Dipterous) genera Tripto- 

 tricha Lw. and Agnotomyia W^ill. Mr. Townsend does not believe that 

 the species of Triptotricha, with only one front tibial spur, should, with- 

 out other distinguishing characters, be generically separated from those 

 possessing two. 



Mr. Fernovv called attention to the ravages of Gastropacha inonacha, 

 particularly in Bavaria, stating that it has probably been introduced in the 

 present instance from Italy. 



General discussion followed on a novel method employed in Europe of 

 collecting and destroying this Bombycid. 



C. L. Marlatt, 



Recording Secretary.
