neiv species of Scoliida. 449 



Discolia vittifrons, Sich. (?). 



(?) Scolia vittifrons, Sich., Cat. ScoL, p. 285 (1864). 



Sichel describes this species from Siam. There are 

 three specimens which agree with the description in the 

 British Museum ; two females from North China and 

 Japan, and a male from North China. The pair from 

 North China expand from 33 to 38 mm. In the male 

 the abdomen is more iridescent than in the females, and 

 the yellow spots on the third segment are placed in 

 front ; in the female the head is entirely black, and the 

 yellow spots stand in the middle of the segment. The 

 female from Japan is considerably larger (expands 

 43 mm.), and has an orange band between the eyes 

 above the antennae, like the male from China. Until 

 more specimens are obtained I prefer to refer these 

 three provisionally to D. vittifrons. 



Discolia punctatissima, n. s. 



Long. corp. 15 mm. ; exp. al. 30 mm. 



5 . Black, sparingly clothed with short black hairs, and very 

 thickly and uniformly punctured, only a small space at the base of 

 each of the lateral lobes of the metathorax being smooth ; abdomen 

 with a slight gi-eenish iridescence. "Wings dull greenish brown in 

 the shade, with black or greenish nervures, but as they are turned 

 to the light, gradually changing, at first along the nervures, and 

 then over the whole surface to the most brilliant violet. 



Hab. Solomon Islands. 



Allied to D. Iceviceps, Smith, from Hong Kong. It is 

 also allied to a specimen from Borneo, in too poor con- 

 dition for positive determination, but which is possibly 

 identical with D. nitidula, Sauss., a Javanese species. 

 It also much resembles D. soror, Smith, from Australia, 

 in which, however, the lateral lobes of the metathorax 

 are punctured to the base. 



Discolia Hecate, n. s. (PL XV., fig. 4). 



Long. corp. 23 — 41 mm. ; exp. al. 44 — 64 mm. 



^ . Black, sides and legs with black hair ; shoulders, scuteUum, 

 and post-scutellum pale yellow ; mesothorax with large punctures, 

 and a groove on each side running forwards from near the corners 

 pf the scuteUum ; mesothorax and first segment of the abdomen
