following sub-genera : Megacronus, Steph., Mycetoporus (these two absorb Bryoporus, 

 not even considered a sub-genus) and Bolitobius. Very long characters are given for 

 these genera, in treating of which, as also of the species, the continental scheme 

 of sub-division, reference, and tabulation is carried to a most perplexing extent, — 

 the whole monograph being a table, and no one item complete in itself. 



The species of the several genera are as follows. 



Hypocyptus : — grandicornis, Fairm. ; unicolor, Rosenh. ; longicornis, Payk. ; 

 rufipes, Kraatz ; rubripennis, n. s. (described from a single $ , France) ; Iceviusculus, 

 Mann. ; lancifer, n. s. ; nigripes, Stephens ; seminulum, Erichs. ; apicalis, Brisout, 

 Gren., Cat. et Mat., (attributed to England expressly) ; discoideus, Er. if. tenuicornis, 

 Ktz., and pictus, Mots., are added as not having been seen by M. Pandelle ; who, 

 however, has had all the other types of Dr. Kraatz's described species of the 

 Tachyporidce sent to him by that author. 



Of these, H. rufipes, Ktz., is apparently possibly only a badly developed 

 specimen of longicornis, to which insect it was attributed with a similar expression 

 of doubt in Wat. Cat. M. Pandelle notes the prior H. rufipes of Stephens, but is 

 wrong in thinking that insect belongs apparently to another genus. It is simply 

 if. longicornis, and is even acknowledged by Stephens himself to be so, in the 

 " Manual," p. 376. if. pulicarius is suppressed as a species ; the only mention of 

 it being that Dr. Kraatz has communicated a large example of seminulum under 

 that name. Erichson's pulicarius is not referred to. The nigripes of Stephens is 

 identified from the description with the pygmceus of Kraatz : but Stephens' insect 

 is longicornis. In the " Manual," he refers his nigripes to Iwviusculus, Mann., and 

 states the hinder angles of the thorax to be " very straight," — a definition which 

 does not agree with the characters of pygmceus. The anisotomoides (Steph.) of 

 Wat. Cat. is not mentioned. In Wat. Cat. it is identified, with a query, with 

 Iceviusculus, Ktz. (these two names are inverted in Mr. Crotch's Cat.) ; it cannot, 

 however, from size and coloration be attributed to M. Pandelle'' s species of that 

 name ; nor does Mr. Waterhouse's type agree with Stephens' description, which 

 states the legs and antennas to be red. It agrees however, specifically, with 

 Stephens' type, which is very immature, and appears to differ from the insect 

 known here as pygmceus, Ktz., solely in the more slender joints of its antennas. 



Conurus : — pedicularius, Grav. ; Lethierryi, n. s. ; lividus, Er. ; littoreus, Linn. ; 

 pubescens, Er. ; fusculus, Er. ; binotatus, Gr. ; Wankowiezi, n. s. ; bipustulatus, Er. ; 

 bipunctatus, Er. Of C. fusculus, M. Pandelle remarks that it seems well to be re- 

 cognised in the immaculatus of Stephens' Illust., v, 1832. As Erichson's insect was 

 described in 1839, I suppose this must be considered as one of the " inconvenient " 

 species. Mr. Crotch, in his catalogue, gives precedence to the Stephensian name. 



Tachypokus : — (Sub-genus Lamprinus) erythropterus, Panz. ; saginatus, Gr. 

 (early spring, ant's-nests) ; hcematopterus, Ktz. ; pictus, Fairm ; (Sub-genus 

 Tachyporus) brunneus, Fab. ; pusillus, Grav. ; tersus, Er. ; transversalis, Grav. ; 

 hypnorum, Fab. ; scitulus, Er. ; humerosus, Er. ; quadriscopulatus, n. s. ; ruficollis 

 Gr. ; Erichsonis, n. s. ; ruficeps, Ktz. ; chrysomelinus, Linn. ; solutus, Er. ; discus, 

 Reiche et Saulcy (solutus var ? ) ; obtusus, Linn. ; and formosus, Matthews (d la mode 

 Francaise, "Mathews"). The unseen species are nigricornis, Gyll., nigriceps and 

 crassicomis, Mann., flavipes, Makl., obscurellus, Zett., and caspius, Mots.
