262 Mr. A.White on some New Insects from the Congo, XXXiy. — Description of some apparently new Insects from the Congo, sent to England hy Mr. Curror, Surgeon R.N., and the late Mr. John Cranch. By Mr. Adam White^ M.E.SS. Lond. and Paris, Assistant Zool. Dep. Britisli Museum. I INTEND giving here a list of such insects as I have seen on the banks of the Congo lately collected by Mr. Curror, surgeon of the "Water Witch/^ and among these^ added to the specimens collected in Tuckey^s expedition, now in the British Museum, I trust that a sufficient number of forms will be found to make the list inter-esting to the student of the geographical distribution of insects. The unfortunate termination of the expedition to explore " the river Zaire, usually called the Congo/' in 1816, under the direc-tion of Capt. Tuckey, is well known ; in the list of supernumeraiy passengers, exclusive of the crew of forty-nine, who went out, occur as the first names those of *^ Mr. Professor Smith, botanist, and Mr. Cranch, collector of objects of natural history." To the zoologist the name of the latter is a well-known sound ; Montagu and Leach have published the results of some of the labours of the Devonshire naturalist. To some of the marine productions of our southern shore, first discovered by him, his name has been applied ; in the preface to a paper on Annulosa, I need only men-tion the two Crustacea, Ebalia Cranchii and the rare Achmis Cranchii, taken by him in Falmouth bay. Should his eulogy be wanted, consult the works of Leach and Col. Montagu. Mr. Cranch died in his 31st year, a victim to the climate of un-healthy W. Africa : he was buried at Embomma along with Mr. Tudor, his comrade. A friend thus writes of him (Introd. to Tuckey's Narrative) : " If I may judge from external appearances, he was an aiFectionate husband and father, a sincere friend, a pious, honest and good man.'' His collections are in the British Museum. Thirty-six only of his insects, according to Dr. Leach, " reached England in a tolerable state, the rest were entirely destroyed by insects and damp." Five or six of these were regarded by Leach as species new to entomologists ; two have been described : one, the Platy-genia Zairica, by MacLeay ; another by Serville from Dej can's collection, the locality of which was unknown ; it is the beautiful longicorn beetle, Euporus strangulatus. Papilio Ridleyanus, n. sp. Pap. ecaudatus fuscus, alis anticis sub-elongatis, supra maculis 5 flavo-miniaceis, posticis supra miniaceis, fusco marginatis nigroque maculatis, posticis subtus caryophyllaceo flavoque tinctis.
