Dr. Marx exhibited two remarkable spiders occurring in our fauna: (i) 

 a representative of the South American genus Nops characterised by hav- 

 ing but two eyes; (2) a puzzling species, the affinities of which he pointed 

 out. It resembles an Epeira, but is altogether different in characters. 



Mr. Schwarz read a paper on the time of flight in Scarabaeid beetles, in 

 which he related an observation made last Jujie by Mr. H. C. Hubbard 

 and himself concerning an undescribed species of Lachnosterna which 

 flies before sunset in the alpine regions of Utah. He added remarks on 

 the flying habits of other species of Lachnosterna and of Scarabaeid bee- 

 tles in general. It appears that in this family the unity in habit regarding 

 the time of flight is generally maintained so far as genera are concerned, 

 and that there are comparatively few exceptions to this rule. 



Mr. Schwarz also exhibited a species of the family Monommidae col- 

 lected on Key West and at Biscayne Bay, Fla., and stated that after a 

 careful study he has come to the conclusion that it is identical with Aspa- 

 thines ovatus Champion recently described from Central America, which 

 adds a new genus to our fauna. Discussed by Messrs. Marlatt, Howard, 

 Mann and Schwarz. 



Mr. Howard read a paper on the " Habits of Molittobia," suggested by 

 Mr. Ashmead's communication at the proceeding meeting. He gave a 

 comprehensive review of the literature, showing all of the hosts of this 

 genus of parasites, proving that it is both parasitic and hyperparasitic. 

 He added an account of the rearing oi M. pelopcei Ashm. from dipterous 

 puparia found in Pelopasus cells by Mr. A. N. Caudell. Discussed by 

 Mr. Ashmead. 



Mr. Banks read a paper entitled "A new genus of Phalangiidae from 

 North America," in which, under the name Caddo nov. gen. agilis n. sp., 

 he described a peculiar Phalangid collected in woods near the seashore 

 on Long Island. Figures representing the peculiar features of the insect 

 were exhibited. 



Dr. Marx gave some remarks on the geographical distribution of spiders, 

 and stated that the Drassidae, formerly supposed to be boreal in habitat, 

 were now found to occur in the tropics in abundance, and that in fact we 

 have not a single family that is entirely northern in range. In the Attidae, 

 however, certain genera may prove to be altogether boreal, but the family 

 is not well worked up. C. L. Marlatt, 



Recording Secretary.
