 submarginali interrupta e atomis nigris, plaga postica nigra 

 penicillata.

 of black speckles in the disk ; a much interrupted submarginal band 

 of black speckles joining on the interior border a patch composed of

a, Philippine Isles. From Mr. Stevens' collection. 



Genus TOPOMESA. 



Mas. Corpus robustum. Proboscis nulla. Palpi robusti, 

 laeves, porrecti, caput sat superantes ; articulus 3us brevissimus. 

 Antenna? breves, latissimae pectinatas. Thoracis tegulae anticae 

 erectae. Abdominis fasciculus apicalis minimus. Pedes breves, 

 robusti; calcaria brevia, valida. Ala? anticae lata?, acutae, vix fal- 

 catae, margine exteriore perparum angulalo ; posticae margine exte- 

 riore postico vix excavato. 



Male. Body stout. Proboscis obsolete. Palpi stout, smooth, 

 porrect, extending rather beyond the head : third joint rounded, not 

 more than one-sixth of the length of the second. Antennae short, 

 very broadly pectinated. Fore tegulae of the thorax erect. Abdo- 

 men a little shorter than the interior border of the hind wings ; 

 apical tuft very small. Legs smooth, short, stout ; spurs short and 

 stout. Wings broad. Fore wings acute, hardly falcate; exterior 

 border very slightly angular in the middle. Hind wings with the 

 hind part of the exterior border very slightly excavated. 



This genus seems to come between Euproctis and Redoa ; it 

 may be distinguished from both by the form of the exterior border 

 of the wings. 



TOPOMESA SUBINANIS. 



Mas. Alba; caput antice cervinum ; thorax vitta brevi pallide 

 ochracea; abdomen pallide ochraceum ; ala? antica? macula 

 media pallide cervina, macula submarginali pallide ochracea 

 cervino notata i margine exteriore ochraceo aut cervino ; postica 

 fimbria ex parte cervina.
