Fam. Mycetophagidae. 



Genus Mycet^ea. 



(Kby.) Steph., 111. Brit. Ent. iii. 80 (1830). 



Mycetcea ovulum, n. sp. 



31. ovata, nitida, pallido-feiTuginea, longe pilosa; prothorace parvo an- 

 gusto, profunde et parce punctato, postice integro (i. e, linea basali 

 transversa baud impresso) sed intra marginem lateralem costa longi- 

 tudinali subcurvata (antice minus distircta) utrinque instructo ; elytris 

 valde profimde pimctatis sed baud stx-iatis; antennis (elongatis gra- 

 cUibus) pedibusque pallido-testaceis. 



Long. Corp. lin. f . 



A most distinct and interesting little Mycetcea, differing (inter 

 alia) from the common M. liirta in its smaller size, more globose 

 form, narrower and much less ample prothorax (which is apparently 

 free from the transverse impression at its hinder margin), and by 

 the punctures of its elytra having no tendency to be disposed in 

 longitudinal rows. I possess a single specimen, captured by Mr. 

 Bewicke at the Cape, but have no information as to its habits. 



Genus Microxenus, nov. gen. (Plate XI. fig. 3.) 



Corpus minutum, Mycetets obovatum, forma et affinitate proximimi, sed 

 antennarum structura omnino diflfert : prothorace lato, ad latera margi- 

 nato sed baud crenulato : alls obsoletis : abdomine e segmentis sex 

 composito, l^no magno lato, ultimo parvo fere immerso. Anten7ice 

 (fig. 3fl) lO-ai-ticulatse, breves, clavatse, inter ocidos insertse ; articu- 

 latis fmo et 2^0 robustis crassis, illo majore crassiore subquadrato, 3tio 

 ad S^'um minutis subaequalibus (8vo vix majore), 9no et lOmo clavam 

 magnam 2-articulatam efficientibus (9no poculifoi-mi, IQmo subovato 

 basi truncate). Lahrum (fig. 3 c?) trans verso-subquadratum, pilosum, 

 apice fere integrum sed ibidem tenuissime membranaceum ciliatum, 

 angulis anticis rotimdatis longe pUosis. Mandibulce (fig. 3 c) magnae 

 validfe corneiB arcuatse, extus ad basin incisse et ante basin valde 

 rotundato-ampliatae, ad apicem incurvfe acutae bitidse, mox intra 

 apicem (in uno saltem) imidentatse, et infra versus basin submembra- 

 nacese. Maxillas et labium baud observavi ; sed palpi maxiUares arti- 

 culate Imo minuto, 2'io paulo majore crassiore, S'io buic latitudine 

 aequali sed breviore, 4'° elongate (reliquis conjunctim vix longiore) 

 subfusifornii,— ?. e. basi ti'uncato et apicem versus leviter acuminato. 

 Pedes (fig. 3 b) basi distantes : tibiis gracilibus subrectis, paulo ante 

 apicem leviter dilatatis : tarsis 4-articidatis, articulatis \^° et 2do inter 

 se arctissime conjunctis (sutura obliqua nisi oculo valde armato baud 

 observanda), illo hoc paido longiore, 2do et Z^° subtus productis, 4'" 

 elongate unyuiculis simplicibus munito.
