d. Ins. Apt., are not such, that one can with certainty see, that 

 he meant by them the same species, that Westking calls Micaria 

 fulgens (Walck.): one might in fact be rather inclined to deny it. 

 I have hovewer, through the kindness of Simon, received a specimen 

 of M. fulgens Westr. from the neigbourhood of Paris under the name 

 of "A/, fulgens (Walck.) 1 , and that name therefore would seem to 

 have, even in France, prescription in its favour for just the species 

 Westring here describes , and of which he has favoured me with spe- 

 cimens of both sexes. As well in these as in a full-grown Swedish 

 i in my collection and in the above-mentioned specimen from Pa- 

 ris, the cephalothorax, on each side behind, has two black spots; 

 these are however frequently absent in younger specimens, in which 

 also the legs are brownish or reddish yellow, with only the posterior 

 metatarsi and the anterior tarsi and metatarsi mostly black. In the 

 fullgrown specimens all the tarsi and metatarsi are blackish, and 

 the thighs also, at least the fore ones, darker at the base. The ce- 

 phalothorax is not twice as long as it is broad (the length is about 

 2'/i, the breadth l'/ 2 millim. in a 3 ad.). The mandibles are covered 

 with copper-red scales, having a metallic lustre. In <J ad., the 

 tibial joint of the palpus is not fully double so long as broad at the 

 base, and it has one little slightly curved tooth just at the apex, on 

 the outer side: the patellar and tibial joints taken together are 

 somewhat shorter than the mandibles. 



Different from this species, though probably often confounded 

 with it, is Mic. formicaria (Sund.) 1832 ') (= Macaria mijrmecoides 

 Ohl. 2 ), and without doubt also = M. aurulenta C. Koch 3 )). A d-spe- 

 cimen, with which I have been favoured by Ohlert, perfectly agrees 

 with a 3 ad., which I captured at Mem in Ostergotland, and with 

 Ohlert's description, loc. cit. , to which 1 beg to refer. A ? jun. 

 I caught at Stockholm, and specimens of the same species, though 

 males only, were found in the island of Gotland by Sundevall. 

 The male M. formicaria (Scnd.) is easily distinguished from M. ful- 

 gens 3 by the cephalothorax being very nearly double as long (2 — 2 % 

 millim.) as it is broad, of almost uniform breadth; the mandibles 

 are destitute of the metallic shining scales, and only covered with hair; 

 they are smaller than in M. fulgens, viewed from in front scarcely 

 broader at the base than at the extremity, where they are trans-
