Mr. J. A. G. Rehii exhibited pictures of the region around 

 Alamogordo, New Mexico. 



Dr. Calvert exhibited a male and a female dragonfly from 

 Guatemala, marked as having been taken together, and belong- 

 ing to an undescribed species of Proioncuj-a.-^ The female has on 

 each side of the dorsal surface of the front part of its mesotho- 

 rax a two-pronged forked process, directed forward and up- 

 ward, one prong lying above the other in a vertical plane. 

 The male has the superior appendages at the apex of the abdo- 

 men two-branched, the branches lying in a horizontal plane. 

 The inferior appendages are longer than the superior, but un- 

 Ijranched. Comparison of the two sexes suggests that in coitu 

 each superior appendage of the male is received between the 

 two prongs of the mesothoracic process of the female, and in 

 this way a perfect interlocking would be the result. Although 

 we have little exact information, it is usually believed that 

 among the Agrioninse (to which Protoneura belongs) it is the 

 protJwra.x of the female which is clasped by the male. The 

 speaker could not recall any other equally complicated meso- 

 iJioracic structure for copulatory purposes on any of the Odo- 

 nata, and few females show such a highly developed copula- 

 tory .structure on any part of the body.

At the May meeting of the Feldman Collecting Social, held 

 at the re.sidence of Mr. H. W. Wenzel, 1523 South Thirteenth 

 Street, fourteen members were present. 



Prof. Smith stated that the larvte which Mr. John.son gave 

 him sometime ago turned out to be Stegomyia fasciata, of 

 which he bred twenty specimens. 



Mr. H. Wenzel stated that the ego^ ma.sses from Anglesea, 

 referred to at the last meeting, turned out to be gras.shoppers. 



Mr. Boerner stated that at Bellevue, Del., May nth, he had 

 taken three species of Dicaelus — dilataius, ambiguiis and ovalis, 

 and upon May i8th he had taken D. dilatatus and ovalis at Ar- 

 eola, Pa. He reported Trechus chalybeus from Westville, N. J. 



* This species, for which I propose the name Protoneura peramans, 

 will be described at length in the Biologia Centrali-Americana.— P. P. 

 Calvert.
