ARADIDAE — KORMILEV 215 



the connexivum are stouter and shorter than in other species. Spiracles 

 of segments ii-v ventral, those of vi and vii lateral and visible from 

 above. Sternmn vii longitudinally inflated (fig. 7). Hypopygium 

 rather large, caudal in position. 



Color: Ochre-yellow, mottled with brown and whitish; scutellum 

 with brown spots around the subbasal lateral whitish spots, at the 

 middle of the lateral margins and on the tip; connexivum bicolorous 

 with brown and white lateral granulation. 



Size: Total length 3.33 mm.; width of pronotum 1.23 mm.; width 

 of abdomen 1.40 mm. 



Holotype: Male (USNM 64205), Bolivia, W. M. Mann, Biological 

 Expedition, 1921-1922. 



Remarks: Calisius bilobatus, new species, is also somewhat allied 

 to conjusus Kormilev, 1953, but differs from it by the bilobate anterior 

 process of the head, different proportions of the antennal segments, 

 and finer and longer granulation of the pronotum and scutellum.

Male: Head (fig. 8) as long as wide through the eyes (24:24), 

 anterior process big, parallel, anteriorl}^ rounded, laterally impressed, 

 roughly granulated, attaining tlie middle of the 3d antennal segment; 

 antenniferous spines stout, dentiform, divaricating and directed 

 slightly downward, almost reaching tip of the first antennal segment; 

 eyes subconical; postocular spines small, tuberculiform, each attaining 

 the outer margin of the eye. The infraocular carinae formed by a 

 few, blunt granules. Vertex with V-shaped, rough granulation; 

 between the latter and infraocular carinae, depressed and with a 

 finer, scale-shaped gi-anulation. Antenna slender, segments with 

 proportions (1 to 4) of 4:5:6:8; the 1st segment subcylindrical, the 

 2d and 3d tapering toward the base, the 3d slightly narrower than the 

 2d, the 4th fusiform. Rostrum not attaining the hind border of the 

 groove. 



Pronotum less than half as long as wide across the humeri (20:43); 

 anterior border trimcate; lateral borders convergent, in the middle 

 slightly emarginate; anteriorly with a single but at the humeri with 

 a triple row of big, blunt teeth. Fore disc with two (1 + 1) posteriorly 

 divergent roM^s of big, erect teeth (each row contains three widely 

 separated teeth). Hind disc with four (2+2) short, parallel rows of 

 similar teeth (the inner rows with two, the outer with four, closely 

 placed teeth) ; fine, scale-shaped gi-anulation dispersed between the 

 teeth. 



Scutellum much longer than wide (62:35), slightly constricted near 

 middle. The basal triangular elevation short, with six (3+3) big,
