basal fourth ; a well-marked black discocellular spot: secondaries 

 with a testaceous discocellular spot. Expanse of wings 8^ lines. 

 One specimen.

S . Micronia gannata, Gue'nee, Phal. ii. p. 26 (\Sbl). 



2 . Micronia aculeata, Guenee, I.e. pi. ];5. fig. 8 (1857). 



Five examples, of which four are males having the dark under 

 surface of M. gannata ; the fifth (which is much broken) is a 

 female, and has the under surface white, as in typical M. aculeata. 

 Although it is true that there are males in which the under surface 

 is white, I have seen numerous gradations from this colour to the 

 dusky brown tint of the type, and I have never yet seen a female 

 with the under surface dark. I therefore agree with Walker 

 in his statement that M. gannata "appears to be the male of 

 M. aculeata." Why this author described a second male as M. acu- 

 leata, with the wings below " plus minusve cinerece," I cannot under- 

 stand, since the only reason for separating the two forms is that the 

 wings below are not "■plus minusve cinerece," but albce.

141. EUPITHECIA, Sp. 



One specimen too much rubbed for description ; it seems to come 

 nearest to E. implicata. 



142. EUPITHECIA TRISTRIGOSA, Sp. H. 



Brown ; wings crossed near the base by an angular black stripe, 

 and close to the base by a greyish band with undulated margins, 

 followed by a central greyish stripe ; an angulated discal black stripe 

 followed by two parallel grey lines ; a slightly undulated submarginal 

 black stripe ; under surface redder than the upper surface, the 

 markings less distinct. Expanse of wings 10 lines. 



Two specimens. The name which I have given it notes the three 

 blacl: stripes across the wings, a peculiarity which distinguishes it 

 from all species which I have seen. The primaries are unfortunately 

 rather badly rubbed ; but traces of the submarginal band are distinctly 

 visible upon the rubbed portion of these wings.

143. Trachonitis punctigeba, sp. n. 



Primaries above olivaceous, base and internal border brown ; two 

 or three ill-defined oblique brownish costal lines ; discoidal stigma 

 lunate, silvery white ; apical third plum-coloured, angulated inter- 

 nally so as just to enclose the discoidal stigma, beyond which it 

 emits a diffused reddish streak into the cell ; a subajiical reddish- 

 bordered olivaceous spot ; fringe pale brown, with a subbasal dusky 

 line : secondaries sericeous greyish brown with cupreous reflections ; 

 fringe whitish, traversed by a grey line : body above greyish brown.
