456 HYMENOPTEBA. 



following three johits united; the second and third joints subequal; the other joints 

 nearly equal in length. Head and thorax opaque, rather densely pilose, finely punc- 

 tured, alutaceous ; the metanotum transversely striated, and with five keels down the 

 centre ; the metapleurse finely rugose. Head elongated, as broad as the thorax ; the 

 occiput margined, scarcely transverse; eyes small, oval, situated in the middle. 

 Prothorax longer than the mesothorax, becoming considerably broader towards the 

 apex. Scutellum with some minute shallow punctures, narrowed towards the 

 apex ; the depression at its base wide and deep. Metathorax longer than the pro- 

 thorax ; the apex margined at the top, and with a slight slope. Abdomen shorter 

 than the thorax, shining, impunctate, pilose towards the apex ; the segments brownish 

 at their point of junction. The mandibles are piceous-red; the tegulse pale testaceous. 

 The anterior and posterior femora are more or less blackish, the intermediate femora 

 marked with black behind. 



CALYOZA. 



Calyoza, Westwood, Trans. Ent. Soc. Lond. ii. p. 56, t. 7. figg. 11 a-c (1837) ; Thes. Ent. Oxon.

I am exceedingly doubtful if the species described below can be referred to Calyoza 

 (an African genus) ; but having only one sex I do not think it is advisable to form a 

 new genus for its reception. 



1. Calyoza (?) westwoodi. (Tab. XIX. fig. 25, <s .) 



Capite, pro- et mesothorace nigro-cseruleis, metathorace abdomineque nigris, antennis fuscis, tibiis tarsisque 



testaceis ; alis fere hyalinis, nervis pallide testaceis. <$ . 

 Long, fere 4 millim.

Antennae apparently 13-jointed ; the basal joint more than double the length of the 

 second ; the third joint not half the length of the second ; the fourth joint nearly as 

 long as the first, produced into a sharp point at the apex ; the fifth joint produced 

 still more, but not forming a ramus ; the succeeding joints each with a rather long 

 ramus, the rami gradually becoming shorter towards the apex. Mandibles large, 

 minutely toothed, the apical tooth not much larger than the others. Front between 

 the antennae acutely carinate ; eyes large, indistinctly margined, situated in the middle ; 

 ocelli in a triangle. Prothorax large, transverse, quadrate, wider than long ; a distinct 

 keel in front and along the edge of the pronotum and above the sternum. Parapsidal 

 furrows complete, sinuated. There is a large fovea on either side of the base of the 

 scutellum, the two fovea? being united by a shallow furrow. Wings with the median 

 and submedian cellules complete ; the radial cellule open at the fore margin ; the other 

 cellules obsolete ; there is an indistinct prostigma.
