Stoll's description of rosea,^^ from Amboina is so brief that even with 

 the aid of his figure Httle can be made out of it. It is very apparent, 

 however, that it has much longer wings than apalamnus, which latter 

 has very short wings in both sexes. 



(^. — Size rather small; form moderately elongate; surface glabrous. 

 Head very large, almost twice the width of the pronotum, oblong, 

 slightly and evenly constricted in the posterior portion; occiput with 

 a broad shallow longitudinally disposed sulcus, another of similar 

 character extending posteriorly from the eye and another on the side 

 of the head; oceUi obsolete; eyes hemispherical; antennae slender, 

 filiform, about equal to the anterior femora in length. Pronotum 

 oblong, about twice as long as broad, very sUghtly broader anteriorly 

 than posteriorly, transverse sulcus centrally placed, lateral portions 

 with a broad shallow longitudinal depression extending almost the 

 entire length. Mesonotum slender, slightly expanding anteriorly and 

 posteriorly, over tliree times the length of the pronotum, surface obso- 

 letely tuberculate; median carina replaced by a very weak sulcus. 

 Tegmina ovate; apex rounded; median protuberance extremely low; 

 venation very irregular and somewhat reticulate in character. Wings 

 short, not reacliing to the middle of the third abdominal segment; 

 costal and mediastinal regions with the transverse nervures distinct 

 and parallel. Abdomen bacilliform; eighth dorsal abdominal segment 

 shghtly longer than the seventh, both of which are somewhat tectate; 

 ninth segment compressed, carinate, apical incision deep and circular, 

 the inferior lateral lobes strongly dentate; cerci about equal to the 

 ninth segment in length, fihf orm, apex acuminate ; subgenital opercule 

 reaching to the tip of the eighth dorsal segment, cymbiform, the apex 

 moderately acuminate. Limbs rather slender. Anterior femora equal 

 in length to the head, pronotum, mesonotum and tegmina, basal flexiu-e 

 slight, apical portion of the inferior surface with four spines; tibiae 

 shghtly longer than the femora; metatarsi half again as long as the 

 remaining tarsal joint. Median femora equal to the mesonotum and 

 haK of the pronotum in length, apical spines four in number, three 

 placed anteriorly, one posteriorly; tibiae equal to the femora in 

 length; metatarsi shghtly longer than the remaining tarsal joints. 

 Posterior femora slightly shorter than the four basal abdominal seg- 

 ments, the apical spines six or seven in number, one at the extreme 

 apex placed posteriorly; tibiae shghtly longer than the femora; meta- 

 tarsi about equal to the remaining tarsal joints in length.
