108 THE ENTOMOLOGIST. 



This species has never been adequately described ; and 

 Sehletterer queries its synonymy with his new Stephanus palles- 

 cens, which is incorrect. An examination of the broken type in 

 Mus. Brit, (which was not labelled as such) shows the whole 

 outer orbits to be broadly pale stramineius ; the anterior legs 

 infuscate, with the tibiae basally ferruginous ; the occiput arcu- 

 ately transrugose, with a slight longitudinal sulcus ; the pro- 

 thorax apically entirely glabrous, discally deplanate and laterally 

 vallately elevated; the semiannular smooth, with a few apical 

 transcarinas ; the metanotum covered with large circular and not 

 confluent punctures, but no areae ; the hind femora black with 

 their apex only beneath and laterally red ; the basal half of their 

 tibiae also red ; the mesopleurae subglabrous, with a few large 

 superficial punctures ; the second and third flagellar joints of 

 equal length, and the first one-third shorter; the mandibles are 

 fulvous and, most noticeably, the whole face below scrobes, 

 together with the inner orbits above them, pale stramineous. 

 The hind tarsi appear to be triarticulate and the specimen, con- 

 sequently, a 2 . 



Superficially it resembles my S. rabripes from the same 

 locality. 



The type was captured in the Solomon Islands during the 

 voyage of H.M,S, " Herald" in 1856, and has hitherto remained 

 unique. But, along with the above >S'. rnbripes, C, M. Woodford 

 captured a second female there about 1886 ; this has the abdo- 

 men smooth, 10 mm. in length, with the trans-striate petiole 

 5^ mm., the second segment basally constricted and slightly 

 rugulose, and the black terebra 15 mm. in length. Unlike the 

 type, its hind femora are black only basally above. 



Dia>tephanus tertianus, sp. nov. 



$ . Head finely reticulate throughout ; posterior tubercles and 

 vertical carina small ; cheeks much longer than scape ; temples 

 smooth ; posterior margin of head simple. Second and third flagellar 

 joints of equal length and about half as long again as first. Neck of 

 prothorax longitudinally sulcate, laterally obliquely carinate ; semi- 

 annular part microscopically sculptured and dull, without any 

 smooth posterior margin ; mesonotum entirely destroyed by pin. 

 Scutellum dull and diffusely punctate. Mesosternum shining, finely 

 alutaceous ; mesopleurae alutaceous and sparsely punctate ; meta- 

 pleurae finely transcarinate, not separated from median segment, 

 which is finely reticulate and sparsely punctate. Abdomen 7 mm. 

 and petiole 3 mm. in length, with petiole transaciculate and shorter 

 than the remaining segments, which are dull ; terebra 10| mm., or 

 rather shorter than l)ody, entirely black. Hind legs with coxae 

 narrow, dull, and apically transaciculate ; femora dull, tridentate ; 

 tibiae longer than femora, constricted to middle. Wings hyaline; 

 stigma lanceolate, centrally translucent, nervures brown. — Black:
