Mr. A. White on some new Lamdlicorn Beetles. 39 



Africa contains many curious CetoniadtB, differing much from 

 each other in the armature of the head of the male. Into none 

 of the many divisions of this section g-ivcn in the papers of Mac- 

 Leay, Gory and Percheron, Du])ont, Hope, Laporte, Sehaum, 

 Westwood, Burmeister, orDr. T.W. Harris of Boston, U. S., does 

 the following insect seem to me admissible, and I accordingly cha- 

 racterize it as a new subgenus. The greatest number of the species 

 of Goliaths are indigenous to W.Africa from Senegal to the Congo. 

 Far up in the interior of S. Africa Dr. Andrew Smith discovered 

 the beautiful species named after him by MacLcay, and subse- 

 quently in the same region, i\Ir. Burke, the Earl of Derby's col- 

 lector, found the Cheirolasia Burkei and Ceratorhina Derbiana of 

 Mclly, figured and described in that useful JMagazine for these 

 " notabilia " of entomology, the ' Arcana Entomologica ' of West- 

 wood ; in this work also is described and figured the Amaurodes 

 Passerinii, obtained l)y Mr. j\lelly from ^lozambique, and now 

 from a part of Africa, which may yet furnish other species, I 

 have an opportunity of describing a species belonging to a small 

 collection made by Dr. Both, the indefatigable naturalist Avho 

 accompanied Sir W. C. Harris on his embassy to the Court of 

 Shoa. For permission to do this I am indebted to Dr. Horsfield of 

 the East India House, audit is after him that I would name this 

 apparently new form of Cetonia. It seems to me to come near 

 Dicronocephalus and Nanjcius, between which and Mecynorliina 

 it may be placed. To Inca, the male has a considerable resem- 

 blance at first sight, and the British Museum collection has from 

 W. Africa a form closely resembling this Brazilian genus which 

 was sho^ii to the Secretary of the Entomological Society, who 

 described and figured it in his 'Arcana,' INIr. MacLeay indeed 

 regards Inca and DicronocepJudus as somewhat allied, unlike Bui'- 

 meister, who places the former nearer Trichius. The species be- 

 low is probably the insect referred to in the appendix of Harris's 

 ' Highlands of Ethiopia/ vol. ii. p. 411, as "one notable /wca, the 

 male of which is armed with a powerful head excrescence, and 

 lives principally on the sap of wounded trees."

Head of male (figs. 1, 3) with the clypeus elongated and turned 

 up; the clypeus is very deeply divided as far as the middle (somewhat 

 as in Narycius, Dupont), the two divisions are slightly angulated, 

 and each is distinctly notched at the end : over and in front of 

 the eyes, the sides of the head are elevated, and the antennae 

 spring from a notch under this raised part. In female (fig. 3) the 

 head is quadrangular, the edge of the clypeus in front abrupt, 

 slightly sinuated in the middle, the sides somewhat dilated. Tho-
