nevei" met with a case of anomaly in which an entirely new organ has 

 been formed. Dr. Selous intends, I believe, to present the specimen to 

 the Natural History Museum, since it is an interesting insect from any 

 point of view. 



Ajjion breviatum, Desbr. This insect is regarded by Herr 

 Wagner as an anomalous form of A. pomonse, Fab. It may readily 

 be separated by its minute size (length, 2-2| mm.) and comparatively 

 cylindrical thorax, w^hich has the base almost straight. Herr Wagner 

 refers a $ specimen taken by me at Deal, to this insect. The two 

 specimens standing in the Power collection as A. opetimm, Bach, must 

 be referred to this also, and Mr. E. A. Butler has several examples. 



Apion mediamiM, Thoms., is the small form of A. curtirostre, 

 Grerm. (^=humile, Grenn.), in which the rostrum is shorter and thicker 

 and the elytra more inflated behind in both sexes than in what we 

 must regard as the type-form. It is quite common.

I am very pleased to be able to bring the following distinct and 

 interesting species of Ila'plotlirips forward as British, both fi'om the 

 neighbourhood of Oxford : —

Comes nearest to H. aculeatus. 



Colour very deep brownish black : antennte and legs as in H. aculeatus. 



Head about 1'55 times as long as the prothorax and 1'35 as long as broad; 

 slightly naiTOwed posteriorly. Antennae only_l'35 times as long as the head. 

 Posterior ocelli widely separated, practically touching inner margins of eyes ; 

 anterior ocellus forwardly directed. Postociilar bristles weak. Mouth-cone 

 bhint, reaching half-way aci'oss the prosternum. Prothorax 1'85 times as broad 

 at hind angles as long. Wings clear, except for a slight touch of brown at
