Larentia Oeneiformis, Harvey, Plate 11, fig. 5. 



$ . — Wings entire ; upper surface ashen or cinereous with a smoky tinge ; 

 costal region and terminal portions of the fore wings darker ; primaries with 

 three white and broad bands, marked on costa but discontinuous ; the third 

 (outer median) more continuous, angulated at vein 5 and indistinctly discern- 

 ible towards the internal margin ; the first and second bands are approximate, 

 discontinued ; the costal region above the subcostal nervure is here reticu- 

 lated ; fringes white, distinctly cut with dark at the extremity of the ner- 

 vules up to and within the depressed and rounded apices. Terminally the 

 nervules are darker marked ; hind wings smoky ashen, with white fringes as 

 on fore wings ; below the primaries are largely smoky ashen, but along the 

 costal region the three white bauds of the upper surface again appear, the 

 costal region is tinged with olivaceous and beautifully striated with black, 

 leaving the apices whitish with costal black dots ; the hind wings are entirely 

 covered with irregular and fine black striations on a white ground ; a median 

 white band can be made out, followed below costa, and again on internal mar- 

 gin, by more distinct striae on an olivaceous ground ; fringes on both wings 

 tinged with reddish; thorax ashen with two white vittae; front dark; the 

 secondaries have the cell closed, outwardly prolonged inferiorly ; vein 5 

 equally strong.

 wings are covered by numerous wavy black lines, followed by pale shades,
