on last segment consisting of four horny, 

 reddish-brown, more or less curved, trans- 

 versely corrugated ridges on each side, a 

 small pit just above and between them; a 

 swelling or prominence below them which is 

 bounded inferiorly by a crescentic transverse 

 furrow, the margin of the segment below 

 furrow being more or less strongly notched. 

 Length, 19 to 12 mm.; width of 6th segment, 

 15 to 6.5 mm. Described from five specimens 

 perhaps not fully grown, collected Oct. 10.

DOHRN AND BURMEISTER. 



Two Nestors of entomology have recently 

 passed away within two days of each other, 

 born in the first and dying in the last decade 

 of the century. Dr. C. A. Dohrn was born 

 in 1S06 and Dr. Hermann Burmeister in 1807 ; 

 the former died May 4, the latter May 2 last. 

 Dohru was especially known as a coleopterist 

 and as the head and front of the Entomological 

 society of Stettin, Germany. Burmeister oc- 

 cupied many fields, not only in entomology, 

 but in general zoology, in geology and espec- 

 ially in paleontology during the past 30 

 years, since his appointment to the direc- 

 torship of the National museum of Buenos 

 Aires. He was buried at the cost of the 

 state and the President of the republic was 

 present at his funeral. Dr. Carlos Berg 

 another entomologist of distinction, long his 

 assistant, succeeds him as director of the 

 museum. 



PROCEEDINGS OF SOCIETIES. 



CAMBRIDGE ENTOMOLOGICAL CLUB. 



13 Mav, 1S92. — The 171st meeting was 

 held at 156 Brattle St. Mr. S. H. Scudder 

 was chosen chairman and Mr. A. P. Morse 

 secretary pro tempore. 



Mr. A. B. Mayer was elected to active 

 membership. 



Mr. S. H. Scudder called attention to a 

 short discussion by Emery in the February 

 Bulletin of the Society Vaudoise (v. 27, p. 

 258) on the origin of the ant fauna of Europe, 



This bot must occasionally continue 

 all winter in the animals, as small ones, 

 apparently this species, were taken from 

 cotton-tails shot Oct 24 and 29. 



On Oct. 14, a jack- rabbit was shot 

 which had a small sac beneath the skin, 

 apparently containing young bots. 

 Closer examination revealed only re- 

 mains of small bots, which had died 

 from some cause. 



a result of his studies of the ants found in 

 Sicilian amber as compared with those of 

 the amber of Samland and the existing fauna 

 of Europe. The existing fauna he divides 

 into three groups, a boreal, an Indian (those 

 having Indo-Australian and South African 

 affinities), and a cosmopolitan, and remarks 

 regarding the first two that in passing from 

 the north southward or from the presenttime 

 to the amber epoch, the boreal group dimin- 

 ishes and the Indian group increases in im- 

 portance ; the former is absent from the 

 Sicilian amber and the latter in the existing 

 Scandinavian fauna. He is of the opinion 

 that an Indian fauna inhabited Europe in 

 eocene time and that a new fauna, derived 

 from the polar regions, advanced upon it, but 

 was checked in its southward march by the 

 sea which then crossed middle Europe, so 

 that it never reached so far as Sicily although 

 it left its impress on the fauna of the Baltic 

 amber. 



Mr. Morse exhibited a specimen of that 

 rarity, the male of Pelecintis polycerator, 

 taken by him at Provincetown, Mass., in 

 September. He also showed two males of 

 Colias interior collected at the summit of 

 Kearsarge Mountain, near North Conway, 

 N. H., July 2, 1891, and several specimens of 

 Colias philodice showing variations in the 

 discal spot on the upper surface of the fore 

 wings; these, in one male, were almost en- 

 tirely absent, and, in a white female, very 

 large and triangular with the apex and 

 longest sides directed outward.
