Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 2G5 



garden at Quinta de Sao Joao, near Fanchal, — a locality in which 

 it was afterwards abundantly captured both by Mr. E. Leacock 

 and Mr. Bewicke. It agrees precisely with specimens in my 

 possession from France and Austria — unless it be, perhaps, that 

 the Madeiran examples are, on the average, just perceptibly 

 smaller. 



Fam. Mycetophagidae. 

 Genus Myrmecoxenus. 



Chen-olat, in Silb. Rev. Ent. iii. 267 [script. Myrmechixenus] 



(1835). 



The genus Myrmecoxenus is usually assigned to the Lathri- 

 diada, to several of the members of which (especially Corticaria) 

 it has a great outward resemblance; nevertheless its quadri- 

 articulate feet, and the other details of its structure, seem to me 

 to point to the MycetopharjidcE as its more correct location, and 

 to such groups as Microchondrus (i. e. Symbiotes) and Mycetoea 

 as perhaps its nearest aUies. Indeed, M. Jacquelin-Duval has 

 already placed it \yide Gen. des Coleopt. d^Europe, ii. 223] in 

 juxtaposition with these genera, having, however, formed a sepa- 

 rate family (the Mycete'ides) for their reception, distinct from the 

 MycetophayidcB proper, — a step which it might perhaps be desi- 

 rable to adopt, though it is scarcely necessary to do so in a small 

 local fauna. I may just remark that, in spite of its great external 

 resemblance to the Corticaria, it may be known, inter alia, by 

 its less abruptly clubbed antennrc (the four apical joints of 

 which, instead of only three, are gradually, though distinctly, 

 thickened), and by its quadri- (instead of tri-)articulate feet, — 

 of which, moreover, the hinder ones have their basal joint much 

 elongated. 



Myrmecoxenus picinus, Aube. 



M. rufo-piceus, subnitidus, ])arce cinereo-pubescens, ubique dense et 

 sat fortiter punctatus ; prothorace transverso-subquadrato, postice 

 vix attenuate ; elytris paulo obscurioribus ; auteauis pedibusque 

 testaceis. 



Long. Corp. lin. vix 1. 



Habitat ^laderam australem, a Dom. Bewicke supra urbem Funcha- 

 lensem captus. 



Myrmechoxenus picinus, Aube, Ann. de la Soc, Ent. de France (2itme 

 st'ric), viii. 330 (1850). 



M. rufo-piceous, slightly shining, sparsely clothed with de- 

 cumbent cinereous pile, and with the entire upper surface closely, 

 regularly, and rather deeply punctured, — the punctures on the 

 head and prothorax being just perceptibly less dense and deep
