A fine general collection of Ilymenoptera Aculeata, con- 

 taining 6io specimens. Some of these have been found by 

 Col. Bingham to be new species. Other Hymenoptera : 

 5 Chrysididae, 13 Chalcididac, and 3 other Terebvaniia. 



The following Orthoptera : 2 Forficulidac\ 23 Blattidae. 

 198 Aa'idiidae, 23 Locustidae, 6 Gryllidac, 47 Mantidae, and 

 I Phasinid. Also i Locustid and i Blatta from the Umfuli 

 district (1899). 



The following Rhynchota : 10 Hemiptera and 3 Homoptera. 



Thirteen Diptera : i Mantispa (Neuroptera), 10 Coleoptera. 



The following fine additions to the bionomic scries, espe- 

 cially the parts illustrating Batesian and Miillerian Mimicry, 

 Fifteen Hemiptera, forming components of various mimetic 

 groups : 2 Reduviids (Hemiptera), a Longicorn and a Can- 

 tharid beetle, all dark iridescent blue-black, and resembling 

 an important group of Aculeate Hymenoptera. The wonderful 

 group of insects mimetic of the well-known Ethiopian Lycid 

 beetles, with a tawny colouring anteriorly and black poste- 

 riorly, formerly presented by Mr. Marshall, has now been 

 greatly strengthened by 8 beetles, 4 moths, 2 Hemiptera, 

 3 Ichneumonids, and 2 Aculeate Hymenoptera. Thirty-four 

 specimens are divided between the following groups, the 

 models of which appear always to belong to the stinging 

 Hymenoptera : (i) black insects with yellow or red head and 

 sometimes thorax, and in some species black and yellow legs — 

 Aculeates, Ichneumonids, Hemiptera, beetles, flies ; (2) greyish 

 black anteriorly, red-brown posteriorly — Aculeates and an 

 Asilid fly ; (3) black with red or yellow apex to abdomen 

 — Aculeates, Bombylid fly; (4) black ant-like group — ants, 

 Coreid and Reduviid Hemiptera. 



A small proportion of Mr. Marshall's generous gift, which 

 is here gratefully acknowledged, has been accidentally 

 transferred to the catalogue for 1900 instead of 1901 to 

 which it properly belonged. Hence his donation for the 

 latter year appears smaller than it actually was, and that for 

 the former year larger in the same degree. Inasmuch as the 

 printed locality labels on the specimens remain strictly 

 accurate and contain a statement of the correct date of pre-
