and fourth to eighth segments inclusive articulated to form an arc. These 

 striking abnormalities and the segmental proportions as illustrated. 



Maxillary palpi four-segmented. First segment minute, longitudinally 

 ovoid; second arcuate, with a cylindrical basal peduncle which is narrower 

 than first segment but which gradually at first and then rapidly widens to 

 from a swollen apical third ; third segment short, transversely triangular with 

 an evenly convex external face and a short subacute internal face ; fourth seg- 

 ment obliquely truncate at base, both external and internal faces evenly con- 

 verging to subacute apex, this segment longer than second and wider than 

 third, with an apical palpal cone. 



Pronotum rounded-hexagonal, wider than long. No lateral foveae but with 

 a median, free, small, circular, nude fovea at basal third. Basal pronotal margin 

 simple. 



Elytra each with two small, perforate, circular, nude basal foveae. The 

 sutural fovea at origin of deep, entire sutural stria. Discal fovea at origin of 

 deep discal stria which extends four-sevenths of elytral length (length of elytra 

 measured from the acute-triangular scutellum). Elytral flank with no sub- 

 humeral fovea, no carina and no stria. 



Wings long (nearly three times as long as elytra when fully extended), 

 strong, finely pubescent with margins having much longer setae (in dry speci- 

 mens the membranous surface granular and iridescent) . 



Abdomen with first tergite nearly twice as long as remainder of abdomen 

 from a strictly dorsal view, with a pair of strong, slightly arcuate apically and 

 therefore slightly divergent, discal striae which are separated by one-half total 

 tergite width and one-half as long as the segment (discal striae measured from 

 a male paratype). Abdominal margin narrow but well-developed. Five visible 

 tergites. Five visible sternites but these made out with difficulty because of 

 their construction: first visible very long, medianly more than three times as 

 long as the remaining four sternites combined, the apical margin of this first 

 sternite gradually produced so as to vault over the second and third visible 

 sternites; second, third, and fourth very narrow medianly; fifth (terminal) 

 sternite also medianly produced posteriorly to fit into concave apical margin 

 of terminal tergite. 



Intermediate coxae separated by an oblong, truncate extension of the 

 mesosternum. Posterior coxae distant. Sternal foveae IV and V, metaepistema 

 and associated sutures as in Drasinus cisinsularis. Metasternum tumid above 

 the articulation of each posterior leg and medianly concave. 



Posterior tarsi elongate, slender, subcylindrical; two-thirds as long as 

 tibiae; first tarsomere minute, one-sixth as long as second; second tarsomere 

 elongate-subcylindrical, longer than third; third tarsomere elongate-cylindrical, 

 bearing apically a single long, arcuate, sharp claw one-third as long as tarso- 

 mere. Anterior and posterior tibiae bearing an apical pubescent process. Inter- 

 mediate (mesothoracic) femora very complexly modified, the dilation, arma- 

 ture and excavation as illustrated. Tibiae of all legs, anterior and posterior
