A NEW SPECIES OF ODYNERUS. 13 



fuscous spots at apices of longitudinal veins to apical areas ; head as 

 long as breadth between eyes, and including eyes much narrower than 

 base of raesonotum, anterior margins of vertex of head almost at right 

 angles to front ; greatest breadth of tegmiua about one-third of length. 

 Long. excl. tegm., ? , 37 millim. ; exp. tegm., 125 millim. 



Hah. Fiji Islands (Crowley Bequest, Brit. Mus.). 



This description is based on two female specimens. The 

 species conforms to all the characters of the genus Saivda, with 

 the exception of the more elongate tegmina. For absolute generic 

 identification a male example is of course necessary. 



DESCEIPTION OF A NEW SPECIES OF ODYNERUS 



(ANCISTROCERUS) FKOM THE CAPE DE VEEDE 



ISLANDS. 



By p. Cameron. 



Oclynerm (Ancistrocerus) atlanticus, sp. iiov. 



Black ; almost the apical half of the clypeus, its sides above 

 obscurely, the under side of the antennal scape, of the apex of the 

 flagellum more obscurely, the upper basal half of the pronotum, 

 tegulae, the basal segment of the abdomen except a semicircular mark 

 on the basal slope, the apical fourth of the second segment, its sides 

 broadly at the apex, the line becoming gradually narrowed towards the 

 base, and the legs, except the coxfe and trochanters, red. Wings 

 hyaline, tinged with violaceous, the nervures black. 2 . Length to 

 end of second abdominal segment, 9 mm. 



St. Vincent, Cape de Verde Islands (J. J. Walker). 



Basal segment of abdomen cup-shaped ; its suture indistinct ; the 

 greater part of the basal two ventral segments are red. The punctua- 

 tion on the first segment is fine, close, distinct ; the second is finely 

 punctured on the sides and apex ; the others are more distinctly but 

 not deeply punctured. Head closely, rugosely punctured, and thickly 

 covered with white pubescence ; the punctuation on the clypeus is 

 wider, more scattered ; it is stronger on the upper than on the lower 

 half ; the apical incision is shallow ; the sides forming stout blunt 

 teeth. The punctuation on the front runs into striations. Thorax 

 strongly, closely punctured, and thickly covered with white pubescence ; 

 the base of pronotum transverse, the sides angled but not projecting. 

 There are two longitudinal furrows on the apical third of the meso- 

 notum. The upper half of the sides of the metanotum roundly project, 

 almost forming longish rounded tubercles. The sides of the clypeus 

 are not keeled. The first abdominal segment is larger than usual ; 

 the second is longer than its width at the apex ; it is narrowed at the 

 base, being thus clearly separated from the first. The second cubital 

 cellule in front is as wide as the space bounded by the recurrent and
