1891.] LYCiENIDiB OF THE SOLOMON ISLANDS. 365 



M. Semper and others ; but on the underside it is a brilliant metallic 

 golden yellow, which is not shown in Felder's figure. 



Thysonotis chromia, sp. n. (Plate XXXII. fig. 3.) 



Male. Upperside silky violaceous blue, costa and outer margins 

 very narrowly and evenly black ; cilia black ; tail black, tipped with 

 white. Underside : fore wing creamy white, with the costal margin 

 broadly black ; outer margin narrowly black near apex, gradually 

 widening towards outer angle ; an indistinct marginal whitish line, 

 and a distinct submarginal white line thickening at each nervule. 

 Hind wing : costa pure white from the base, gradually tapering 

 towards the apex ; below that a broad black band between the costal 

 and subcostal nervures reaching from the base to the apex ; below 

 this a broad white band from the inner margin running to a point 

 at the apex, even on its upper edge, zigzag on its lower ; following 

 this a rather broad black band, and again beyond this a submarginal 

 row of black lunules bordered inwardly with large white crescent- 

 shaped lunules ; the four lower ones being more or less covered 

 with brilliant shining caerulean-blue scales. A rather broad distinct 

 white marginal line from the apex to the anal angle, intercepted with 

 black at each nervule. 



Head, thorax, aud abdomen concolorous with wings ; antennae 

 black, annulated with white ; legs black and white. 



Expanse l-^-^ inch. 



Fauro I. Maravo I. 



I have not seen the female of this insect. It is allied to T. sper- 

 chius, Feld., but has many points of distinction. 



The specimen figured is from Fauro I. 



Epimastidia, gen. nov. 



Allied to Thysonotis ; neuration the same ; antennae somewhat 

 more slender and more gradually clavate. Upperside of hind vnng 

 with subcostal nervure clothed from base for about two-thirds its 

 length with long slender hairs. Underside with no metallic spots 

 or markings. 



Type Lyccena inops, Feld. 



In the British Museum collection E. inops is placed in the genus 

 Pithecops, with which it also agrees in neuration, but I think from its 

 general appearance it is more nearly allied to Thysonotis. It may 

 perhaps be found convenient to retain the name Bonis for the group 

 of which the Papilio danis, Cr., is the type, as they seem to be 

 coarser-scaled and more robust insects. 



Epimastidia contains tailless insects, Thysonotis tailed and tail- 

 less, and Danis tailless species. 



Epimastidia arienis, sp. n. (Plate XXXII. fig. 6.) 



Male. Upperside uniform shining cserulean blue, with the outer 

 margins of both wings rather narrowly blackish brown ; hind wing 

 with the costal third whitish brown, lighter towards the margin. 

 Underside pure creamy white, with the outer margins of both wings
