514 Mr. G. Meade- Waldo^s revision of the species of 



^. Similar, but with a large triangular mark between the an- 

 tennae, the lower orbits, the clypeus at base and apex, mandibles 

 basally, and tergite 2 with apical fascia, pale yellow. 



Length 11 mm. 2 $ ?, 1 c?. 



Nyasaland : Mlanje, 2300 ft., vi.-x. 1913 {S. A. Neave). 



Very near 0. marginipunctatus, but differs as follows : 

 Wings unicolorous, suffused with fuscous, abdomen entirely 

 smooth. 



0. (Lionotus) aureosericeus, sp. n. 



$. Niger, vix luteo-variegatus ; mandibulis basi, postscutello 

 nonnumquam, segmentique mediani lateribus infra, luteis; abdo- 

 mine aureosericeo ; alis inf useatis. Long. 10 mm. 



General appearance black; the mandibles basally postscutellum 

 more or less and lateral angles of median segment below, pale 

 luteous. Clypeus rather longer than broad, convex, pyriform, the 

 apex subemarginate with two small lateral teeth ; anterior margin 

 of pronotum truncate, the lateral angles acute ; scutellum flat, not 

 raised; lateral angles of median segment acute. Punctured as 

 follows: head, pro- and mesonotum, scutellum postscutellum, 

 pleura above, and median segment above, coarsely, abdomen both 

 dorsally and ventrally, with fine punctures ; pleura below, tegulae, 

 axillae, truncation of postscutellum and median segment below 

 impunctate. Wings infuscate, especially along the costa. 



Head and thorax clothed with silver-pruinose pilosity, abdomen 

 with golden pile. 



Length 10 mm. 3 ? ?. 



Uganda : W. of Victoria Nyanza, Buddu, 3700 ft., 

 ix. 1911 (type); Bugoma Forest, Unyoro, 3700 ft., xii. 

 1911; Matiana to Entebbe, i. 1912 {S. A. Neave). 



The silver and golden pilosity on the head and thorax 

 and abdomen respectively in this species is very fine and 

 only visible in certain lights. The type specimen has a 

 yellow transverse fascia on the postscutellum, the other 

 two specimens, both of which are stylopised, have only 

 the faintest traces of yellow.

$. Niger; scapo, prothorace, pedibus (coxis trochanteribusque 

 exceptis) ferrugineis; clypeo basi, abdominis segmentis 1 et 2 

 maculis lateribus, tergitibus 1-5 fasciis apicalibus interruptis, 

 sternitibus 2-5 margine externo, luteis ; alis inf useatis. Long. 1 1 mm. 



Clypeus as broad as long, convex, pyriform, the apex formed by
