Hah. North Borneo : Kina Balu {Whitehead). 



I liave seen only two male examples of this. Like A. hi- 

 formis, it lias the" lower surface of the body coppery green 

 and the legs metallic crimson, but the upper surface is more 

 green and the body is proportionately narrower.

On a Collection from the Solomon Islands. 



The species described here were collected by ]\lr. W. W. 

 Frogffatt, of Sydney, and sent to me for identification. One 

 or two were sent to the British Museum by Mr. Woodford 

 many years ajjo. As might be expected, they are nearly 

 allied to New Guinea species, and many wide-ranging species 

 were included, a list of which will be published by 

 J^Ir. Froggatt. 



Thynnus larharus, sp. n. 



^ . Clypeus large, very broadly truncate at the apex, the 

 angles not produced, longitudinally striated, deeply punctured 

 between the strite, pointed at the base and joined by a very 

 short narrow carina to the broadly rounded apex of the inter- 

 antennal carina. Labrum finely punctured and ciliate at the 

 apex, narrowly truncate on the apical margin, not emarginate 

 or bilobed, projecting much beyond the clypeus. Head finely 

 punctured rugulose, a deep frontal sulcus not reaching the 

 anterior ocellus, the space between the posteiior ocelli arid the 

 eyes shining and almost smootii. Antennfe of almost even 

 thickness throughout, shorter than the thorax and median 

 segment combined. Thorax and abdomen closely punctured, 

 most finely and closely on the pronotura and sides of the 

 mesonotum, pleur* finely punctured. Pronotum narrowed 

 anteriorly; the anterior margin almost as wide as the head, 

 raised, with a transverse groove behind it. Scutellum large, 

 very broadly rounded at the apex and very feebly subtuber- 

 culate in the middle of the apical margin. Median segment 

 obliquely truncate from the postscutellum, the surface of the
