ENTOMOLOGICAL SECTION. V 



nine inches apart so that the boxes may rest on the long edge, the 

 shelves may be enclosed in any sort of closet or cabinet. In these 

 boxes the specimens are arranged in the following manner : faint 

 pencil lines are drawn from one side of the box to the other dividing 

 it into five or six equal portions according to the size of the speci- 

 mens, beginning at the upper left corner of the box I place say four 

 specimens side by side and so on down that column and then the 

 other divisions in succession. 



Such an arrangement has given me greater satisftiction than any 

 other I have tried. In justice to Mr. E. W. Janson of London, I 

 must state that the pattern of the box is due to him, but experience 

 has taught me that only those boxes will stand our variable atmosphere 

 which are made of native lumber and seasoned and made here. 



The pin now used by me and very nearly all of my friends and 

 correspondents is that made by Klaeger of Berlin, and is in length 

 1.34—1.40 inch, (34—35 mm.) 



The question of the pin and box is almost the first difficulty met 

 by every one at the outset of his entomological career, and as all of 

 us have been compelled to find out for ourselves what seemed to be 

 best, I have thought it not improper to place before the entomologists 

 of America the results of nearly twenty years of experiment and 

 expense. 



Mr. E. T. Cresson exhibited specimens of three new species of 

 hymenopterous insects contained in the collection of the American 

 Entomological Society, and described them as follows: — 



Aulac^s edittis. — J. — Black; head subglobose, broad behind the eyes, 

 cheeks and back of ocelli smooth and shining, face pubescent, vertex beneath 

 ocelli feebly punctured ; palpi pale, except base ; antennse rather longer than 

 head and thorax, scape sometimes ferruginous beneath ; thorax above coarsely 

 transversely vvrinkled, mesothorax subpyramidal in profile, anterior and lateral 

 margins of middle lobe acutely carinate especially at angles, broadly rather 

 deeply eraarginate medially; wings hyaline, stained with dusky yellow, nerv- 

 ures and stigma black; legs ferruginous, tarsi sometimes yellowish, coxse and 

 trochanters black, posterior femora sometimes tinged with fuscous; abdomen 

 as long as head and thorax, ferruginous except base of first segment ; ovipositor 

 as long as body. Length .55 inch. 



Hab. — Nevada, (Morrison); California, (Edwards). 



Anlacus abdomiiialis. — ?. — Black; head subglobose, broad behind 

 the eyes, cheeks and back of ocelli smooth and shining, face pubescent, vertex 

 beneath ocelli punctured; antennae as long as head and thorax, entirely 

 black; thorax above coarsely transversely wrinkled, mesothorax in front sub- 

 pyramidal in profile, the anterior margin prominent, carinate and broadly not 

 deeply emarginate medially ; wings hyaline, nervures and stigma black; legs
