32 Mr. P. Cameron on new Aculeate Fiymenoptera 



Head alutaceous, the lower part of the front and the mouth 

 ref^ion densely covered with silvery pubescence, the furrow 

 below the ocelli is deep, and there is a similar furrow on the 

 front, commencing near the top. Mandibles broadly rufous 

 near the middle. Pro- and mesonotum closely punctured; 

 the scutellum punctured, but not so closely. Median segment 

 closely, irregularly reticulated, the reticulations more distinct 

 at the base ; the apex is transversely striated, the striaj are 

 distinctly separated ; the furrow is narrow but distinct. Pro- 

 pleurai closely punctured ; the mesopleurre are distinctly, but 

 not so closely punctured ; metapleuraj obliquely striated all 

 over. The sternal process has a distinct hollow at the base ; 

 the fipex of the hollow is conical ; the apical incision is 

 triangular. Wings hyaline, with a yellowish tint at the 

 base ; the nervures blackish ; the first cubital cellule is equal 

 in length to the second ; the upper (and larger) part of the 

 first transverse cubital nervure has a sharply oblique slope ; 

 the recurrent nervures are separated by the length of one third 

 of the top of the first cubital cellule. Legs pruinose ; the 

 calcaria black ; the tarsal spines dark rufous. Abdominal 

 segments pruinose on the apices. 



Spanolarea, gen. nov. 



Mandibles incised on the underside near the base. Antennfe 

 long, slender; the second joint pilose. Eyes large, con- 

 verging above, reaching to the base of the mandibles ; the 

 folds on front large ; the ocellus elongate, triangularly 

 produced in front. Tarsi long, the posterior twice the length 

 of the tibijB, which are sparsely spined ; the tarsal spines 

 long ; the claws are long, longer than the apical joint of the 

 tarsi, roundly curved, and without a tooth. Anterior femora 

 roundly dilated, narrowed at base and apex, liadial cellule 

 wide and truncated at the apex. Wings reaching to the 

 apex of the abdomen. Apex of pronotum reaching to the level 

 of the mesonotum. Median segment as long as the pro- and 

 mesothorax united ; there is no furrow on the mosopleurfe. 

 Abdomen shorter than the thorax ; the pygidium smooth, 

 except at the apex, glabrous, except slightly at the apex ; 

 the sides are sharply keeled throughout. 



The chief characteristics of this genus are tiie long antennae 

 and tarsi and the almost spineless tibia\ In the form of the 

 legs it comes close to the genus Leptolarra here described, 

 but the tarsi want the tooth found on the claws in that genus, 

 from which it differs further in the much longer antenme, in 

 the longer median segment, and in the apex of the pronotum
