This species is most easily recognized by the head, from the dorsal 

 aspect, being one-half as long as wide, with the scrobe cavity deep, 

 the metacoxa with a completely glabrous outer dorsal surface, the 

 abdominal petiole short, and the abdomen rather strongly compressed. 

 S. lecta is quite similar in structure to the genotype, and apparently 

 also to S. indica Mani, recently described from India.^^ 



Description. — Black with large yellow spots; anterior and meso- 

 legs, frons, two large anterolateral areas of dorsum of pronotum, 

 broad anterolateral spots of mesopraescutum, tegulae, all of meso- 

 scutellum except narrow apical band, metatrochanters and meta- 

 femora except variable spots on outer surface, yellow. 



Female : Unknown. 



Male: 4.5-5.5 mm. Antennal scape (fig. 9, /) with apex not quite 

 reaching level of ventral margin of anterior ocellus, pedicel slightly 

 longer than segment 4, ring segment one-half length of pedicel, 

 segment 5 slightly shorter than 4, segments 5 to 10 equal, 11 and 12 

 slightly shorter than 10, 13 equal to 10; scrobe cavity deep, edge 

 carinate at ventral and dorsal margins, dorsal carina located just 

 ventral to anterior ocellus; inter antennal projection with a minute 

 dorsal carina; frons deeply but scatteringly punctured laterad of 

 scrobe cavity, ventrad of antennal bases a few irregular transverse 

 carinae present, area laterad of scrobe cavity slightly produced 

 cephalad; frontal tentorial pits located just laterad of antennal 

 bases, slightly above level of ventral margin of scrobe cavity; width 

 of malar space one-third height of compound eye; frontogenal 

 suture arced; genal area posterior to suture with rather indistinct 

 oblique rows of large punctures; combined widths of compound eyes 

 slightly less than interocular width at level of antennal bases; left 

 mandible with two acute teeth, ventral one larger, right mandible 

 with three teeth somewhat blunted at apex, ventral one largest; 

 diameter of posterior ocellus slightly less than one-half interocellar 

 space; head, when viewed from dorsal aspect, slightly greater than 

 one-half as long as wide. 



Dorsum of thorax densely and deeply pitted, areas between punc- 

 tures minutely reticulated; pubescence mostly short, longer at poste- 

 rior margins of pronotum and mesoscutellum ; anterolateral angles of 

 pronotum weakly carinate, anterior dorsal margin acarinate; parap- 

 sidal furrows obscure ; prepectus narrow, tonguelike, reaching tegula ; 

 apex of mesoscutellum provided with a very narrow, mesally depressed 

 lamina; metepisternum strongly and densely punctured, spaces be- 

 tween punctures glabrous, pubescence long and fine; metacoxae gla- 

 brous on outer dorsal surface, elsewhere minutely, scatteringly punc- 

 tured and setose; metafemora globose, outer surface minutely reticu-
