above figure has been made. The only variable character I have 

 observed is in the colour of the prominent anal appendages, which 

 are either totally black, or testaceous with their apices black. 



1860. Drona pennata, sp. n. 



Body and legs flavescent ; face as seen between eyes san- 

 guineous ; abdomen beneath with three prominent basal black 

 spots (one central and one on each lateral margin) ; eyes piceous ; 

 tegmina semihj'aline, the venation flavescent, basal third of 

 extreme costal margin and apical third of inner margin to costal 

 area fuscous, the apical half of costal area flavescent ; wings 

 semihyaline, base orange-yellow with, a posterior black spot, apical 

 t\\o-thirds semihyaline, with the posterior margin and an oblique 

 discal fascia fuscous. 



Length excl. tegm. 3 ; exp. tegm. 14 millim. 



Hah. Tenasseriiii ; Myitta (DoJierti/). 



Of this distinct and beautifully marked species I possess only 

 one specimen, and that in somewhat inditt'ex-ent condition ; I can, 

 therefore, only describe the colour-characters. 



Genus INTERAMMA. 



Interamma, Walk. J. Linn. Soc, ZooL x, p. 118 (1867) ; Melich. 

 Horn. Faun. Ceylon, p. 60 (1903). 



Type, /. ascendent, Walk., from the Island of Morty. 



Bistrihution. Oriental and Malayan Eegions. 



" Body slender ; head cultriform or extremely compressed and 

 dilated vertically, as long as the thorax, with two edges above 

 and with one edge beneath; eyes prominent ; antennae cylindrical, 

 more than half the lengtli of the head, forked at the base, third 

 ioint very shoi't; pronotum short, arched; mesonotum not keeled ; 

 legs short, slender ; tegmina and wings narrow ; tegmina with an 

 irregidar submarginal line of transverse veins." (Walker.) 



I have only copied Walker's short and imperfect generic 

 diagnosis, because I believe more than one genus is included in 

 the species he enumerated. The two specimens of the Ceylonese 

 species here included are mutilated in the cephalic process, A^hich 

 prevents exact generic identification, and I have therefore followed 

 Melichar in regarding the species as belonging to the genus 

 Interamma, 



1861. Interamma I'ubrofasciata, Melich. Horn. Faun. Ceylon, p. 61, 



t. ii, f. 8 (1903). 



Dark stramineous ; head and pronotum much suffused with 

 sanguineous ; mesonotum with the lateral margins and three 

 central longitudinal fascise sanguineous ; tegmina with the base 

 of costal margin, the posterior margin, an ii-regularly oblique
