23,4 Baker: Malayan Jassoidea 359 



Length of face (Plate 1, fig. 6, c) less than the width across 

 eyes. Face of the S. tagalica type, the strong median ridge 

 running out at clypeal suture; basal border of front concave in 

 facial view. Supraocular carina weak but traceable across 

 anterior portion of crown near and parallel to subocellar carina 

 which sharply borders anterior margin of crown, the latter carina 

 depressed to the level of the discal concavities of vertex ; ocellus 

 distant the length of its own diameter from eye. Length of 

 vertex less than half width between eyes; concavities of vertex 

 shallow, with a strong complete median white carina. Front in 

 lateral view (Plate 1, fig. 6, 6) strongly and rather abruptly 

 swollen on lower half. Pronotum (Plate 1, fig. 6, a) about three 

 and a half times length of vertex, the anterior lateral margins 

 into the width a little more than three times; marginal carina 

 (lateral view) and pleura similar to those of S. malaya. Inter- 

 sections between thimble pittings of pronotum narrower than in 

 S. maculata but also low and smooth; median carina distinct 

 only on anterior half, very strong where it crosses the anterior 

 depression. Margin of basal cell of clavus about a half again 

 longer on the commissure than on the anal margin. 



Borneo, Sandakan (Baker). 



Signoretia benguetensis sp. nov. Plate 1, fig. 7. 



Female pale ochraceous; dorsum of abdomen, except seg- 

 mental margins, black ; median carina of front and lateral ridges 

 brownish ; two small spots at apex of vertex and two large spots 

 at base black ; a median longitudinal piceous band on pronotum, 

 extending from transverse depression to base of pronotum, 

 broader posteriorly. Tegmina translucent, the veins of corium 

 and clavus slightly infuscated. Length, 6.5 millimeters. 



Male with dark markings more deeply colored and more ex- 

 tensive. Frontal carina black, all bordering carina? of vertex 

 broadly deep black; pronotum largely washed with blackish. 

 Tegmina palely infuscated throughout, the veins darker, claval 

 veins blackish. Length, 6 millimeters. 



Length of face (Plate 1, fig. 7, c) less than width across eyes. 

 Face similar to that of S. bilineata, but the front in lateral view 

 (Plate 1, fig. 7, b), though swollen, is evenly curved from base 

 to apex and not strongly suddenly protuberant below; antero- 

 lateral depressions of clypeus narrow, the latter with a dark 

 spot at middle; lateral ridges of front very strong. The 

 supraocular carina is weak anteriorly and joins subocellar carina
