ENTOMOLOGICAL NEWS [Oct., '13 



accurate and more comprehensive description of the structure 

 of a typical mammal than has been hitherto attempted." No 

 other volume appeared, however. 



In a brief notice which he read on April 10, 1895, at a me- 

 morial meeting for his university colleague, John A. Ryder, 

 Dr. Jayne refers to his own work, "in arranging part of the 

 collections of the [American] Entomological Society" at a 

 time when he first made Ryder's acquaintance. This must 

 have been about 1876. He became a member of the Society 

 August 9, 1875, in the year before that body came to occupy 

 quarters in the building of the Academy of Natural 

 Sciences. His association here with Drs. LeConte and Horn 

 is indicated in the opening paragraphs of his two Coleoptero- 

 logical articles, Descriptions of some monstrosities observed in 

 North American Coleoptera (Trans. Amer. Ent. Soc. VIII, 

 pp. 155-162, pi. IV, June. 1880) and Revision of the Dermesti- 

 dae of the United States (Proc. Amer. Philos. Soc. XX, pp. 

 343-377, pis. 1-4, August 18. 1882). The latter paper is the 

 more pretentious, and in it the author says: r 'The arrange- 

 ment of genera is, substantially, that already well known, save 

 only the necessary alterations incident to the introduction of 

 two new genera, \Acolpns and A.rinoccnts]. The specific 

 classification is almost entirely original." Three new species 

 of Attagenus, one of Acolpus, two of Trogoderma, one of 

 Axinocerus, were described. In both of these papers the au- 

 thor's name appears as Horace F. Jayne, but he dropped the 

 "F." in later years. 



Dr. Jayne, in virtue of his position as secretary of the Fac- 

 ulty of Biology of the University of Pennsylvania, in 1888, 

 will ever be associated in my memory with the happy beginnings 

 of my own collegiate studies in zoology and with his willing 

 assumption of the task of major examiner for the doctor's de- 

 gree, a post made suddenly vacant by the death of Ryder. 

 Those kindly recollections have remained unclouded, and it is 

 with genuine sorrow that this brief notice is written in some 

 slight acknowledgment of him who has passed away.
