54 [March, 



Larger (length 10-2r)-ir5 mm.). More snddenl}- widenod at the shoulders 

 and more abruptly narrowed behind. Crown less pointed. Upperside 

 brownish-yellow closely and coarsely punctured with black, a suffused 

 pale stripe next the costa nearly to the half-lengtli ; a., blackish near the 

 middle and before the apex; a more or less distinct suffused blackisli 

 biind from the middle of tlie costa to the blackish line near the middle 

 of aa, the veins in and beyond this baud brown; tlie pubescence, except 

 tliat of the clavus, ert-cto-pateut, and producing a hoary appearance, 



maculatd, n. sp. 



A large gathering of A. macnlata from the New Forest in Juno, 

 submitted to me bv Mr. Hugli Scott, contained many pale, more or less 

 tonoral examples which, but for their shape and pubescence, might be 

 regarded as A. salic/'s. Fully coloured specimens of A. mamdata have a 

 very distinct appearance, especially in life. In September 191S, I took 

 A. macnlata in numbers off Salix cinerea in a wood in the Forest of 

 Bean without getting a single example of A. salicis. The hitter I only 

 meet with on a nari'ow-leaved Sal/\r, having the appearance of S.fraqilis, 

 on tlie Wiltshire side of this county and in the Vale of Gloucester. 



Oucopsis carpinicola, n. sp. 



Face, ill the lateral aspect, comparatively llat. Dorsal rim of elvtra, as a 

 rtde, entirely whitish. ])ark baud on the crown cut short by the lateral black 

 points, and giving oft" from its lower edge a well-defined black line wliich 

 reaches to the level of the base of the specula. Black line on the inner edge 

 of the hind tibiae not reaching lieyond the apical third and usuall}^ much 

 shorter than this. Jjungth o'0-5'66 mm. 



Lives on hornbeam. Common at Colesborne, and doubtless else- 

 wliere. 



J. Sahlberg (Notiser Fenn. xii, p. 123) describes a Pnlinpsis 

 carpini living on hornbeam ; but since, according to the description, 

 the face of the latter is just as convex as that o^ ffavicollis L., and the 

 insect is otherwise chieily distinguislied from the latter by having the 

 hind margin of the pronotum scarcely visibh^ emarginate, it cannot well 

 be the same as ours, which has that part quite as deejjly notched as it is 

 mflavicoUis. 



In dealing with insects of this genus it should be remembered that 

 the convexit}^ of the face is always greater in the female than in the 

 male; if female a veil anae o\' carpinicola be compared with \Vi?\<djiavi- 

 collis in this respect tlic difference is only small, but if females of each 

 are compared the distinction is very evident. 



Oncopsis avelhniae. n. sp. 



Face, in the lateral aspect, comparatively flat. Dorsal rim of elytra 

 blackish between as and a.i. Dark band on the crown extending bnyond tlie
