is equal to the length of the first tergite, in f rater the length is greater, 

 exceeding the first tergite in about the ratio 17 : 14. 



The anal somite appears shorter and broader, ^vith the annulus less 

 shortened ventrally. Body in general broader in proportion to length. 



Number of segments (female type), sixty-three. 



Length, near 12 mm.

 Lasema (W. M. Mann). 



Distinguishable easily from the two preceding species, which it 

 resembles in the marked concavity or elevation of the venter above 

 the edges of the tergites, in the form of the head. The latter is shorter 

 in proportion to the depth at the upper end and about equals the length 

 of the first tergite. Whereas in S. f rater the head in profile is straight, 

 or even slightly concave, from near the level of the eyes ventrad and 

 in senior is likewise straight or very nearly so, in the present species 

 the line bulges decidedly convexly a little below the If'vel of the 

 antennae. The hairs on the face proportionately longer and more 

 evenly distributed. The coloration is much as in S. frater, being light 

 ferruginous with lighter, more yellow markings but without the vio- 

 laceous mottlings of many species. Hairs of dorsum short, numerous. 



Number of segments (female type), seventy-three. 



Length, near 11 mm. INlore slender than frater.

Type.— M. C. Z. 4,900. Paratype.— M. C. Z. 4,901. Solomons: 

 Fulakora (W. ISI. ISIann). 



General color pale fulvous of a slight greenish tinge with anterior borders 

 of segments darker, a weakly outlined pale spot in dark region on each side 

 below. Antennae duskj- over a light background, darker distallj'. 



Head subtriangular in outline, the Kne of face in profile not indented at 

 level of antennae, weakly convex to lower end; sides nearly straight but 

 slightly incurved a little above tip and above that weakly convex. Ej'es 

 more than twice their diameter apart. Antennae unusually stout and heavy, 

 strongly clavately widened to fifth article, the sixth moderately narrowing 

 distad, the seventh verj^ small; exceeding head below by sixth and seventh 

 articles or by these and part of fifth article. Head and antennae subdensely 

 clothed with hairs of moderate length.
