3. — Helojjhorns fallax Kuwert ? 



Kuwert places at the head of his characters of H. fallax : " End- 

 halfte des letzen Palpenghedes scharf dunkel.'\ That is not the case 

 in any of the specimens I am referring to in his species ( indeed, in some 

 of them, there is no darkness of the palpus), but as the character is 

 not of great importance, and I think it possible that they may be 

 Kuwert's species, I treat them as such. 



Of shoi't form, broad (nearlj' l.V mm.), 3 mm. lonj^, the channel of vertex 

 linear and miniite, the maxillary palpi only moderately long, the head and 

 thorax of dark metallic colour, the elytra dark ferrviginoiis, not marked with 

 black, the sculptixre of npper svirface coarse, and the insect but little shining. 

 The head small, thorax strongly transverse, hind angles very obtuse, grooves 

 narrow, median one not broader in the middle, front part slightly flattened on 

 the middle in front, everywhere strongly granulose, but on the most elevated 

 part of the disc the granules sub-ol)literated. Elytra deeply striate, the inter- 

 stices rather broad, some of them slightly more elevated, the punctures somewhat 

 large, sub-crenate, the lateral margin strongly outstanding. Legs red, antennal 

 club yellow, maxillary palpi but little infuscate at the tip. On the under-surface 

 the flanks of the elytra are very distinctly visible. 



Four specimens from the Castelnau collection, in which they were 

 labelled " H. nanus Schiippel, Alsace," and four others from Pontarlier 

 (Deville) in the Champion collection detennined as fallax by Deville, 

 indicate this as a somewhat variable species, the colour of the thorax 

 varying from brassy to a dark steely -metallic tint, the legs and palpi 

 varying a little in colour, and also the sculpture of the median intervals, 

 which is sometimes much eifaced. Kuwert is mistaken in supposing 

 that the legs bear no hairs. The species is really closely allied to 

 H. nanus, but the aedeagus, which is by one-half more elongate than 

 in nanus or in laficollis, leaves no doubt as to it being quite apart from 



them.

PhyUotreta diademata Foudras, in England.— A little misunderstanding 

 exists Avith regard to this insect. Foudi-as, in describing it, attached chief 

 importance to the sculptiire of the vertex, which he says is " impunctate, 

 tenuissime granulate, separated from the forehead bj' a punctate line." Hence, 

 no doubt, the name diademata. Weise in the " Ins. Deiitschlaud " also makes of 

 this almost the chief character of the species. 



Newbery introduced the species as British in 1908 from Devonshire (Ent. 

 Mo. Mag., p. 148), and also tabulated it relying on that character, but remarked 

 that " the characters derived from the punctuation of the head do not appear 

 to be sufficiently constant." C. G. Lamb shortly after found a specimen in
