Five females. (Osakura), (No. 13). 



32. PACHYPROTASIS PALLIDIVENTRIS, new species. 



Female. — Length, 9 mm.; expanse, 16 mm.; ratlier robust; surface 

 of body shining; head, thorax, and abdomen of about equal width; 

 clypeus very broadly and evenly emarginate; tips narrow, pointed; 

 labrum much broader than long, somewhat emarginate at tip; antennae 

 very slender, elongate, third joint much longer than fourth; claws 

 deeply and rather evenly notched at tips; sheath very narrow, rather 

 obtusely pointed ; general color black, marked on the head, thorax, and 

 lower surface of body and legs with very light yellow, almost white ; 

 on the head the white occurs as a narrow line on the inner orbits and 

 bends at right angles posteriorly so as to inclose a large quadrate 

 black spot, including the ocelli, and covering the entire vertex; in front, 

 the white extends from the base of the anteunte anteriorly, including 

 all of the mouth parts and cheeks; on the body, the white is limited to 

 the posterior upper edge of the pronotum, the tegulaj, line about the 

 middle lobe of mesonotuni, the mesoscutellum, postscutellum, meta- 

 scutellum, and the ventral surface of the thorax and abdomen with the 

 exception of a central black baud extending along the center of the 

 sternum and the venter of the abdomen ; legs, including coxa3 and tro- 

 chanters, for the most part yellowish- white; the anterior pairs of legs 

 have a broad black band on the upper side of the femora, tibiie, and 

 tarsi; the posterior legs have the outer third of the femora black, and 

 also the tip of the tibiic and all the tarsi; the basal two- thirds of the 

 posterior tibijie are yellowish brown ; the extreme tip of the abdomen 

 is whitish and there is a slight line of white on the posterior edge of 

 some of the dorsal terminal sclerites; wings hyaline, or nearly so, with 

 the veins and stigma dark brown or black. 



Male. — Much smaller and more slender than the female ; length, 7 mm. ; 

 expanse, 15 mm.; antenna; as long as body; structural characters in 

 general as in female; color as in female except that the venter of 

 abdomen is entirely white on the apical half of the abdomen and the 

 posterior legs correspond in color with the anterior legs, except that in 

 addition to the band on the upper side of the femora there is a corre- 

 sponding band on the lower side also; the abdominal segments above 

 are more distinctly marked with white than in the case of the female.
