which are tri-articulate, as tetramerous. I dissected it with great care 

 in 1860, and gave the result in the "Ann. of Nat. Hist." for April of 

 that year ; but since the " Annals " may not be readily accessible to 

 all your readers, perhaps the following extract will not be out of place. 



" The little Anommatm 12-striatus bears so strong a primd facie 

 " resemblance to Aglenns that it has been universally, with one 

 " exception, placed alongside that genus, amongst the Colydiadce. 

 " Nevertheless, the various authors who have thus tacitly acknowledged 

 '' its afl&nities seem merely to have followed blindly in the wake of 

 " Erichson, whose description of its structural details was, as M. Duval 

 " has recently well remarked, both loose and inaccurate ; and, after a 

 " very careful dissection of it, I agree with M. Duval that it should 

 " undoubtedly be assigned to the Latridiidce. True it is, that its robust 

 " limbs and abruptly clavated antennae are not in accordance with the 

 " normal members of that family ; but then, on the other hand, neither 

 " are they universally indicative of the Colydladce ; whilst even among 

 " the Latridiidce such genera as Cholovocera and Meropliysia afford us 

 " an abundant precedent for the supposition that the terminal joints of 

 " the antennae may sometimes, in that group, become absolutely lost 

 " by uniting into a densely compact mass. Then, with respect to the 

 " tarsi of Anommatus, having mounted them in balsam for the micro- 

 " scope, I believe that Duval is perfectly right in regarding them as tri- 

 " articulate, instead of quadri-articulate (as stated by Erichson). The 

 " basal joint is certainly a little constricted on its under-side, but even 

 " polarized light will not show the merest rudiment of a suture ; and I 

 *' have not the slightest hesitation, therefore, in concluding it to be a 

 " single joint, and the whole foot to be consequently tri-articulate — 

 "which is almost universally the case with the Latridiidce. The 

 " antennse are composed of only nine joints besides the club, — which 

 " latter is extremely compact, and with no annular traces on it what- 

 " soever. Hence, although we assume that the two ultimate joints are 

 " fused into it, we must practically regard the entire number (i.e. the 

 " recognizable number) as diminished from the normal standard, — 

 " whicli is, likewise, perfectly in accordance with the generality of the 

 " Latridiidce, in which the antennal joints vary from eight to eleven. 

 " All points considered, I believe that Anowmatiis is more nearly akin 

 "to the (likewise blind) Langelandia anojihtJialma than to almost any 

 " other, perhaps, of our European genera." 



The non-development of eyes is, also, greatly characteristic of 

 these imiiiediate groups of the Latridiidce. In Langelandia and Anom-
