character exists, and, moreover, there is freqiieutlj in the genus an 

 obscure elevation of the surface just in front of the coxae that may 

 have misled him. Moreover, G-anglbauer in writing of the species does 

 not allude to the character at all. Our British laticoUis is very easily 

 distinguished. It is convex transversely, and has the elytra narrow at 

 the extremities ; the channel of the vertex is linear and obscure ; the 

 maxillary palpi have the terminal joint rather long, very asymmetric and 

 extensively infuscate, the penultimate joint notched to an unusual 

 extent on the inner margin. The thorax broad and a little peculiar in 

 shape, the greatest width is just about the middle, and the hind angles 

 are very obtuse ; the median and sub-median grooves are very narrow, 

 the latter but little sinuous, the sub-external groove rather broader and 

 more irregular, the colour peculiar, the discoidal part steel-blue, the 

 grooves golden, the sculpture at the sides strongly granular, much 

 effaced on the discoidal portion. The elytra are rather dark in colour 

 (in the New Forest examples), but black marks are almost absent, the 

 sculpture deep and regular, the lateral margin distinctly outstanding 

 in the middle. The under-surface very dark in colour, convex, the 

 flanks of the elytra not visible, the pubescence copious, pallid ; the legs 

 a dai'k yellow. The delicate setae of the surface and legs are unusually 

 well developed. The length Sh mm., and not varying a great deal. 

 This description is made from New Forest specimens, of which I have 

 been able to study a very large series, and it is there not a variable 

 species. Some examples from Woking (Walker) have the elytra paler 

 in colour, the general form a little broader, and the jDunctures of the 

 elytra a little larger, but others are like the Brockenhurst individuals. 

 The only other example I have seen is one sent by Sahlberg from Fin- 

 land, and it has the characters of the Woking examples in a very 

 exaggerated manner. 



This appears to be a little known species. It is apparently rare 

 injScandinavia, and though it has been recorded in G-ermany Gangl- 

 bauer doubts the correctness of the records, but he admits its occurrence 

 in Central Russia and G-alicia. Eeitter admits it as German apparently 

 on the faith of the two records doubted by Granglbauer. In Britain it 

 is recorded from only three localities, in southern and central England 

 (Brockenhurst, Woking and Horning). At Brockenhurst it is by no 

 means rare ; but it must be looked for in the early spring, March and 

 April, or in late October. All the spots I know for it become dried up 

 in the summer; they are veiy shallow small pools, or ^lepressions, 



much choked with grass. * r U
