teiiiipe basim versus incrnssato', dor so e bast squamato-piloso, apice nu- 

 diusciilo. Haustellum mediocre, squainatum. Palpi labiales vix

 pressis, tertio tenui, acuto, prioris fere longHiuViHe. Alse eloiigata^,

Head smooth. Forehead, between the antenufc, rather narrow. 

 Ocelli none. Antennae towards the base thicliened, with hairy scales on 

 the bach at the base, with the apex comparatively naked. Tongue of 

 moderate length, clothed with scales. Labial palpi hardly as long as 

 the thorax, rellexcd ; the second joint compressed, with appressed 

 scales; the third joint slender^ pointed, neurli/ as hmcj as the second. 

 Wings elongate, the posterior ovate, with obtuse anal angle. In the 

 anterior wings the lower branch of the apical vein runs into the costa 

 before the a]3ex ; there is no secondary cell, and the subdorsal vein is 

 furcate ; in the posterior wings two veins proceed from the transverse 

 vein. 



We liave but two species in this genus (a third, closely allied 

 to Oliviella, has been met with in Asia Minor) ; being of gay 

 colours, they fly during tlio day (it being found an almost inva- 

 riable rule, that the richly-coloured species of Lcpidoptera fly 

 during the day, when their colours may be exposed to view) ; the 

 flight of B. snlphnreUa is ratlicr straight and sharp, but that of 

 D. OUvielht is undulating and sluggish. Tlie larva of I), sulpliu- 

 refia has been known for some time; it feeds hi decayed and de- 

 caying wood, preferring to place itself immediately beneath the 

 bark, but not disdaining to penetrate deep into the wood itself; it 

 is of an unusually elongated form.

Head bronzy, with a few yellow hairs. Face bronzy. Palpi bright 

 yellow ; terminal joint dark fuscous. Antcnme dark fuscous, almost 

 black, with three white annulations a little beyond the middle. An- 

 terior wings fuscous, with numerous pale yellow scales, especially to- 

 wards the hinder margin; from the base is a short yellow streak near 

 the costa, and another on the fold (continued to beyond the middle in 

 the $ ) ; oit the iuuer margin, betjotid the viiildle, is a triattgidar pale yel- 

 loxo spot, and on the costa nearly opposite is a smaller but distinct pale
