which has, in addition to the branches similar to 

 the others of the other ganglia, large branches 

 from the system of the seventh ganglion. The 

 connectives between the ganglia with the excep- 

 tion of those between the subesophageal and first 

 thoracic and those between the seventh and eighth, 

 get all of their branches from the ganglia above 

 and below them. In the case of the first excep- 

 tion, there are two additional branches from the 

 outside. In the case of the second, all of the 

 connective supply comes from the system of the 

 seventh ganglion. There is in each ganglion a 

 very complete superficial and deep network of 

 large and small branches. The tracheoles in the 

 center of the ganglia are very numerous and very 

 intricately woven together, but in no place was 

 anastomosis found.

The 5X8 card is used as the unit, one side 

 being rather closely ruled, while on the other side 

 is printed an outline map of the state. Each 

 insect is given a card — the divisions into orders, 

 families and genera being indicated by appropri- 

 ate guide-cards. All records as to place and date 

 of capture are written in condensed form on the 

 ruled side, while on the map a dot is placed for 

 each locality. Gradually these records will define 

 the different life-zones of the state and will indi- 

 cate the approximate distribution of each species. 

 Rediscovery of the Bibionid Genus Eupeitenus: 



D. W. COQTJILLETT. 



In 1834 Macquart described Penthetria atra 

 n. sp. from a male specimen in Serville's collec- 

 tion, captured at Philadelphia, Pa., since which 

 time the species has not been talcen again until 

 April 26, 1908, on which date Mr. H. S. Harbeck 

 collected a female specimen at Germantown, a 

 suburb of Philadelphia. Walker, in 1838, referred 

 two British American specimens to this species, 

 but there is no certainty that his identification 

 was correct. Macquart's figure is very faulty. 

 In 1838 Macquart erected a new genus, Eupei- 

 tenus, for tliis species.

The report from the excutive committee was 

 read and, with all its provisions and recommenda- 

 tions, adopted. 



The executive committee announced the election 

 of the following fellows: Samuel W. Williston, 

 Theodore Dru Allison Cockerell, Ephraim Porter 

 Felt, Elmer Darwin Ball, Alexander Dyer Mac- 

 Gillivray. 



Mr. Viereck moved to ask the committee on 

 nomenclature to define what constitutes a species 

 and variety, taking into consideration what the 

 ornithologists have done, and that they bring the 

 same up before the Commission on Nomenclature 

 of the International Congress of Zoology one year 

 before the next meeting of that congress. 

 Adjournment. 



At 8 P.M., in the assembly room of McCoy Hall, 

 the annual public address was given before the 

 society by Dr. E. B. Poulton, Hope professor of 

 zoology in the University of Oxford, on " Mim- 

 icry in the Butterflies of North America." The 

 speaker was introduced by Vice-president Smith. 

 A large and appreciative audience was in attend- 

 ance. The address was illustrated by many beau- 

 tiful colored slides.

ASHMEAD 



William Harris Ashmead, naturalist, honorary 

 fellow of this society, died on October 17, 1908. 

 We, his colleagues, would hereby give expression 

 to our sorrow in the loss of a leader and a friend 

 — one who gave himself unsparingly to the ad- 

 vancement of the science we cherish, who made 

 himself by his zeal and industry one of the fore- 

 most students of the Hymenoptera in the world, 

 and who furthered our progress by his numerous 

 and valuable papers and by the prompt and gen- 

 erous aid he lent to every student who asked his 

 expert knowledge and assistance. We gratefully 

 acknowledge our debt to him, and we desire to 

 place on record this testimonial of our esteem for 

 liim as a man, our pride in his successful career, 

 our high regard for his scientific work, and our
