Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 265 



garden at Quinta de Sao Joao, near Funchal, 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. 



Chevrolat, in Silb. Rev. Ent. iii. 267 [script. Myrmechixenus] 



(1835). 



The genus Myrmecoxenus is usually assigned to the Lathri- 

 diadce, 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 Mycetophagida as its more correct location, and 

 to such groups as Microchondrus (i. e. Symbiotes) and Mycet&a 

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

 already placed it [vide 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 

 Mycetophagida 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 antennse (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, parce cinereo-pubescens, ubique dense et 

 sat fortiter punctatus ; prothorace transverso-subquadrato, postice 

 vix attenuate ; elytris paulo obscurioribus ; antennis pedibusque 

 testaceis. 



Long. corp. lin. vix 1. 



Habitat Maderam australem, a Dom. Bewicke supra urbem Funcha- 

 lensem captus. 



MyrmecJioxenus picinus, Aube, Ann. de la Soc. Ent. de France (2ieme 

 serie), 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
