autennfe rather short and robust, black, the lower three joints 

 fulvous, the second and third ,joints small, equal, the terminal six 

 joints rather strongly widened, but longer than broad ; thorax 

 scarcely twice as broad as long, the sides nearly straight, obliquely 

 angulate before the middle, very narrowly mai-gined, basal margin 

 oblique at the sides, rathei- sti-ongly produced towards the scutellum, 

 preceded by a shallow transverse sulcus which is l:)ounded at the 

 sides by a deep perpendicular groove, the surface rather convex, 

 somewhat closely and strongly punctured ; elytra with a shallow 

 depression below the base, the shoulders rathei' prominent and 

 smooth, the surface strongly and regularly punctate striate, the 

 interstices impunctate and flat ; under side and legs black, base of 

 tibife and the tarsi more or less fulvous, presternum naiTowly 

 elongate ; witli a longitudinal shallow sulcus. 



Hah. Santa Oatarina, Brazil. 



The short, ovate shape of this species, shoi-t and i-ather robust 

 antennfe, and the produced basal margin of the thorax at the 

 middle agree best with the species at present placed in Hipjntri- 

 phila instead of Creiy'idodera proper ; four specimens ai-e contained 

 in my collection. 



3. Notes on Anthropoid Apes.

[Received December 13, 1904.]

Although, from the eai-liest times, beginning with Hanno's 

 (jrorillce, we find the writings of observers of nature filled with 

 accounts of hairy wdld men, and, in latei' days, many descriptions 

 by zoologists of anthropoid apes, it was only after the appearance 

 of Du Chailhi's book that universal attention was turned to 

 these creatures. 



Prior to 1870, several so-called species both of Gorilla, Anthro- 

 pojnthecus, and Simia auct. had been established, but until lately 

 the majority of zoologists maintained that there was only one 

 rather variable species each of Gorilla,, Chimpanzee, and Orang- 

 Outan. Professor Matschie's articles on the genus GoriUa 

 (Sitzungsb. Ges. naturf. Freunde, 1903, pp. 253-259, and 1904, 

 pp. 45-53) and his articles on the species and races of Chimpanzee 

 (Sitzungsb. Ges. naturf. Fr. 1900, pp. 77-85, and 1904, pp. 55-69) 

 have, however, once more aroused the gi-eatest intei-est in the 

 question of the true status of our knowledge of the anthropoid 

 apes. In the first place. Professor Matschie insists, and, I believe 

 rightly, that the Gibbons {Hylohates) should form a separate
