 fall, and go back to the point from which they departed." 



In the following table, which is drawn up on the principle 

 of taking the most obvious characters rather than the most 

 important, it is thought desirable to include two genera not 

 occurring in the Malayan archipelago — one {Sphadasmus) 

 represented by an Indian species, the other the Australian 

 genus Ilacuris. Thus all the known Asiatic and Australian 

 genera are here enumerated. 



a. No pectoral canal, or, if present, not passing the anterior coxae. 



b. Eyes closely approximate, occupying the whole head or nearly so. 



c. Funicle six-jomted. 



d. Anterior femora linear, elongate. 



e. Scape not nearly reaching the eye Mecopus, Schon. 



ee. Scape extending beyond the eye Tulmithia, n. g. 



(Id. Anterior femora thickened, not, or only mode- 

 rately, elongate. 



/. Propectus canaliculate. 



(7. Second joint of the funicle very long Agametis, Paso. 



gg. Second joint of the funicle scarcely longer than 



the others Gangojris, n. g. 



ff. Propectus not canaliculate. 



h. Second abdominal segment aa long as the third 



and fourth together. 

 i. Anterior coxaj contiguous. 



J. Anterior tibiae compressed, curved, or bisinuate . Dadania, n. g. 

 jO'. Anterior tibiae straight or nearly so. 

 k. Second joint of the funicle twice as long as the 



first Pempheres, n. g. 



kk. Second joint of the funicle not longer than the 



first Phylaitis, n. g. 



ii. Anterior coxae not contiguous C'hirozetes, Pasc. 



hh. Second abdominal segment shorter than the 



third and fourth together Odoacis, Paso. 



cc. Funicle seven-jointed. 



I. Tarsi elongate, linear Emexaure, n. g. 



//. Tarsi less elongate, the three basal joints gradu- 

 ally broader. 

 m. Body rhomboidal or elliptic. 



w. Three intermediate segments of abdomen equal . Brimodn, n. g. 

 nn. Second segment of the abdomen as long as the 



two next together. 



o. Rostrum triangular at the base Osphilta, n. g. 



00. Rostrum cylindrical at the base 31etialma, n. g. 



mm. Body oblong, parallel Heurippa, n. g. 



bb. Eyes not closely approximate, nor occupying 



the whole head. 

 p. With ocular lobes. 



q. Intercoxal process narrowed Nauph^us, n. g. 



qq. Intercoxal process very broad Arachnopiis, Gu^r. 



jyp. Without ocular lobes. 



r. Intennediate segments of abdomen of equal length Sphadasmus*, ^ch'on. 



rr. Second abdominal segment longer than the next 



two together Ilaouris, Pasc.
