sion followed as to the relative value, for purposes of study, of 

 alcoholic and inflated larvae. Mr. Schwarz considered alcoholic 

 preservation best for coleopterous larvae, while Dr. Dyar said 

 that in the Lepidoptera inflated specimens were by far the best. 

 Speaking of ants, Mr. Ashmead recommended for study the 

 papers on these insects by Prof. Wheeler, of the University of 

 Texas. 



Mr. Schwarz exhibited the work of a Scolytid beetle (presum 

 ably Dendroctonus approximattis Dietz) in portions of the bark 

 of Pinusponderisa, illustrating how quickly a tree may be killed 

 by this pest. These specimens were obtained at Flagstaff, Ari 

 zona, during the past summer. This species is the only one 

 which is fatal to the pine in that locality, the other Scolytidas 

 producing only secondary injury. 



Mr. Schwarz also reported that Mr. Barber and himself had 

 taken two species of Myrmecophilous Staphylinidae at Las Vegas, 

 New Mexico, last summer, in the nests of Liometopum species. 

 These were described by Wasmann in Wiener Entomologische 

 Zeitung, XX, pp. 145 to 147, 1901, as Dinardilla liometopi, and 

 Apteronina schmitti, new genera and species, from specimens 

 collected at Cotopaxi, Colorado, by Prof. Jerome Schmitt. 



Mr. Heidemann showed two adults and a larva of the Coreid 

 bug Stachyocne?nus apicalis Dallas, collected by him last August 

 in a sandy field near Washington cit} 7 . This species, though of 

 wide distribution, having been recorded from Florida, Texas, 

 Mexico, Dakota, Colorado, and Missouri, has not before been 

 reported from the District of Columbia, and may be considered 

 as quite rare. 



Mr. Hay showed one specimen of the butterfly Neonympha 

 gemma Hubner, which was taken by him in Nickajack Cave, 

 Tennessee. This seems to be the first butterfly recorded from a 

 cave. 



In regard to the Tree Crickets, Mr. Caudell stated as his 

 opinion that the common and injurious species in the northern 

 States was (Ecanthus fasciattis Fitch, not niveus Serville. 



Dr. Dyar exhibited specimens of the moths and larvae of 

 Triprocris smithsonianus Clem., and presented a description of 

 the larva, the first larva of the genus to be described, as follows :
