Sipyloidea poeciloptera-' n. sp. 



Types.— d^ and 9 ; Island of Obi, Molucca^. [A. N. S. Phila., pre- 

 sented by Mr. Morgan Hebard.] 



As this species does not appear to be closely related to any of the 

 previously known species, I have compared it with the type of the 

 genus. The new form differs from S. sipylits in the smaller size, the 

 very weak character of the granulations on the mesonotum, the some- 

 what slenderer and less coriaceous tegmina, the blunter character of 

 the apex of the ninth dorsal abdominal segment and the more acumi- 

 nate apical portion of the subgenital opercule. 



cJ*. — Size mediiun; form elongate; surface smooth. Head slightly 

 oblong, dorsal surface flat, the occiput wdth a slight median longi- 

 tudinal sulcus; eyes ovate, prominent; antennae slightly exceeding the 

 body in length. Pronotum longitudinal, about twice as long as broad, 

 subequal in width, transverse sulcus in advance of the middle. Meso- 

 notum about three and a half times the length of the pronotum, very 

 slender, very slightly constricted centrally ; surface with a few obsolete 

 granulations and a weak longitudinal median carina. Tegmina ovate, 

 the apex sub-truncate, median protuberance of medium height and 

 rather blunt. Wings equal to the mesonotum and about two-thirds the 

 abdomen in length. Abdomen with the seventh and eighth segments 

 subequal in length, and exceeding the ninth, which is somewhat tectate 

 and apically subtruncate with a very shallow median emargination ; 

 cerci short, stout, subequal, extending but slightly beyond the ninth 

 dorsal segment; subgenital opercule not quite reaching the apex of the 

 eighth dorsal segment, moderately compressed, apex rather broadly 

 rounded. Limbs very slender. Anterior femora equal to about half 

 the length of the abdomen, basal flexm-e slight; tibiae about equal to 

 the femora in length; metatarsi considerably exceeding the remaining 

 joints in length. Median femora equal to the mesonotum and tegmina 

 in length; tibiae shghtly shorter than the femora in length; metatarsi 

 very shghtly longer than the remaining tarsal joints. Posterior femora 

 about equal to the anterior femora in length; tibiae equal to the femora 

 in length; metatarsi exceeding the remaining tarsal joints in length. 



9 . — Size medium. Head suboval, not constricted posterior to the 

 eyes; occiput with a distinct longitudinal median sulcus; eyes ovate; 

 antennae about two-thirds the length of the body. Pronotum as in 

 the male, but the transverse sulcus is not so anterior in position. 

 Mesonotum three times the length of the pronotum, slightly expanding 

 posteriorly, median carina very fine, subobsolete. Tegmina ovate,
