Mr. Comstock spoke on Lycsnidse and based his remarks upon material 

 collected by Mr. Hallinan in the Panama Canal Zone, which region he pointed 

 out as a natural dividing line for many South American species. A beautiful 

 series of specimens particularly rich in Theclas was shown. Mr. Hallinan 

 obtained 51 of the 121 species recorded from the Panama Canal region. In 

 flight Mr. Hallinan mentioned that some of the large iridescent Theclas re- 

 semble Morphos ; others presistently frequent the tops of tall thorn trees where 

 their capture requires much patience and considerable forbearance. Thus of 

 polybe and regalis after a week's trial in the tops only fovir specimens were 

 secured. 



Mr. Shoemaker told of his collecting experience at Washington, D. C, 

 where he spent two weeks last year during June accompanied by Mr. Davis. 

 He obtained abotit 3,000 specimens of Coleoptera and Lepidoptera, many of 

 which were new to his collection. Most of the collecting was done on the 

 slopes of the Potomac, both on the Maryland and Virginia sides. Part of his 

 catch including the following species was shown : Panagccus fasclatus Say, 

 Platynns caiidatiis Lee, Callida viridipennis Say, Odoiitonyx trivittis Germ. 

 Saiidaltis petrophypa Knoch, Chalcolepidius viridipilis Say, Trichius delta 

 Forst., CaUigrapha ainelia Knab, Bellainira scalaris Say, Cacoplia pullata 

 Hald, Statira croceicollis Makl., Neinognatha cribraria Lee, Cirrhophanus 

 triangulifer Grt., Mamestra marinitincta Harvey, Plagiomimicus pityochromus 

 Grt., Acontia aprica How. A large number of Carabidae, Scarabasidse, etc., 

 were captured in bait bottles, of which seventy were planted and regularly 

 inspected. Excepting condensed milk, which proved not very productive, only 

 a mixture of molasses such as collectors of Lepidoptera generally apply to 

 trees was used as bait. 



Mr. Davis showed a number of photographs of the Potomac River region 

 near Washington and also many species of insects of various orders, among 

 them the large bot fly Cuterebra horripilnm Clarke, the rare dragonfly Neu- 

 rocordulia obsoleta Say, and the little cricket Myrmecophila pergaudi, which 

 latter species, he thought, ought to be found in New Jersey if looked for in 

 its habitat — ants' nests. Attention was called to the average larger size in a 

 series of Carabus limbatus Say from Washington as compared with a series 

 of the same species from the mountains of southern Georgia. As an instance 

 of the predicament a collector is apt to find himself in, Mr. Davis cited his 

 experience in the capture of a bettle CaUigrapha amelia Knab. The beetle was 

 observed in a difficult position for capture among the twigs of a bush of 

 nimbark, its food plant. But what rendered proceedings still more difficult 

 was the discovery of a copper head coiled below. Mr. Davis had the satis- 

 faction of exhibiting both beetle and snake. 



Mr. Pollard spoke on the occurrence of Chlorippe celtis at Washington, 

 where at times the butterfly is exceedingly abundant. 



Mr. Davis exhibited twenty-four species of insects that he had found 

 attending the glands on the upper side of the leaves of Popnlus grandidentata 

 and called attention to two of them, a bee of the family Halictidse and a
