Anisotoma fallens, Sturm ; Er., Ins. DeutscH., iii, p. G6. 



For this interesting addition to our Coleopterous fauna we are 

 indebted to Mr. J. J. Walker, who took three examples of it, by- 

 sweeping, at Deal, on 19th September last. The species can only be 

 compared with A. ficrva and ciliaris, being very convex', short-ovate, 

 and with very short antennae ; but it is readily distinguishable from 

 both of these by its smaller size, the much finer and less close punc- 

 tuation of its thorax, and the finer punctuation of the strife and finer 

 and much less close punctuation of the interstices of its elytra, the 

 sides of which are not ciliated. 



I am indebted to Mr. Gr. C. Champion for one of these specimens. 



? Anisotoma aRANDis, Fairm. 



The insect brought forward by myself ^^ith some reserve under 

 this name has again occurred to me at Mickleham : it has also been 

 found at Loughton, and (on several occasions) at Caterham, by Mr. 

 Champion, and (I believe) at Esher by Mr. Marsh. The largest $ 

 that I have seen measures 2\ lines ; the smallest $ If lines. The 

 examination of these further examples, of both sexes (and, in the ^ , 

 of varied development, as usual in the genus), if it do not reconcile 

 my insect with Fairmaire's, at all events convinces me of its validity 

 as a species, for which, if it prove distinct from A. grandis, I propose 

 the name anglica (Stephens's lycoperdi and tuheris being, as I have 

 satisfied myself from an examination of his collection, nothing but 

 cinnamomea) . In its rather flatter build, ferruginous antennal club, 

 which is of looser structure, and has the second joint rather larger, 

 this species, compared with cinnamomea, agrees with the description 

 of grandis : but I find that the punctuation of the interstices of the 

 elytra is of no value as a diagnostic character, some examples agree- 

 ing with Fairmaire's description in having this punctuation very 

 evident, and others being, if anything, less perceptibly punctured 

 than cinnamomea. The thorax cannot be said to be not contracted 

 behind : it is -distinctly less contracted in front than in cinnamomea, 

 being more evenly rounded on the sides, with more rounded anterior 

 angles, and its greatest width being more towards the front, so that 

 it seems more transverse. In the largest and most highly developed 

 (^ (nearly as large as my largest (^ cinnamomea), the posterior femora 

 have the inner apical tooth not so large as the outer one (this inner 

 denticle is in the other males scarcely developed at all), and there is 

 no trace of the small denticles on the under edge of the femur towards
