Hub. Claremont, Calif, [Baker: Pomona coll. 229). 



In the table in Trans. Am. Ent. Soc. xxv. p. Ilj5, this 

 runs out at 10, because the clypeus is yellow and there is no 

 supraclypeal mark except a minute scarcely visible dot. It 

 falls near to S. zoualis (Cresson), known only in the male, 

 but is too different to be its female. 



Sfiinoliella coinpiula, sp. n. 



? . — Length about 8*5 mm. 



Black, with ivory-coloured face-markings and dull yellow 

 abdominal bands ; hair of head and thorax greyish ; face 

 broad ; clypeus (except lower margin, and a j)air of black 

 marks like triangular flags on poles, their points directed 

 toward the eyes), subcircular supraclypeal mark, triangular 

 lateral face-marks (produced above, ending in a sharp point 

 on orbital margin a little above level of antenuee), lower 

 part of labrum, and laige patch on base of mandibles, ivory- 

 colour; flagrllum short and thick, dull red beneath except 

 at base ; me>oihorax shining, sparsely punctured (punctures 

 large and small), impunctate on disc; thorax witljout light 

 markings ; area of metathorax shining, its base broadly 

 dull ; anterior knees with a small yellow spot ; anterior 

 tibiae and tarsi iu front with ferruginous hair. Abdomen 

 with five yellow bands, the fifth broken into two large 

 patches, the others continuous but narrow iu middle, the 

 second with its large lateral expansions broadly excavated 

 on outer side ; venter without bands. 



Hub. Mountains near Claremont, Calif. (Baker ; Pomona 

 coll. 224). 



In my table cited it runs to 6, but falls out on account of 

 th'i peculiar face-markings. In Fowler's table (' Psyche,' 

 Sept. 1899) it luns to S. cincta (Cress.), but that has the 

 face all dark in the female.
