22 i Mr. P. Cameron on new 



area finely rugose at the base, more coarsely transversely 

 rugose before the spiracles, the middle with some stout 

 curved keels, the apex much more closely but not quite 

 so sharply obliquely striated. Mesopleurae closely punc- 

 tured, strongly irregularly striated under the tubercles ; the 

 metapleurse uniformly, somewhat strongly punctured and 

 deeply depressed at the base above. Postpetiole obscurely 

 punctured laterally and furrowed in the middle. Scutellum 

 thickly covered with long fuscous hair; postpetiole striated 

 at the base. 



Agrees closely in coloration with A. rufopetioluta, includ- 

 ing the rufous petiole; may be known from it by the 

 narrower areola, which receives the keel in the middle, 

 while in rufopetiolata it is received clearly above the middle. 



Algathia lutibalteata, sp. n. 



Agrees closely in coloration with A. zona t a ; may be 

 known from it by the black hind coxae, by the base of meta- 

 notum being rugosely punctured, by the areola being rounded 

 at the base and stoutly transversely striated, &c. 



Black ; a small mark on the face below the antennas 

 (broad at base, gradually narrowed to the apex, as long as it 

 is wide at the base), palpi, tegulae, scutellums (except the 

 scutellum at the base), the apex of the first abdominal 

 segment, of the second and third more broadly, the apical 

 two thirds of the penultimate, and the whole of the last, pale 

 yellow. Mandibles black, the apical third rufous. Palpi 

 pale yellow. Pour front legs fulvous, the tarsi iufuscated, 

 the coxae and trochanters pale yellow ; the hind coxae black, 

 the top and more or less of the inner side rufous; basal joint 

 of trochanters rufous, apical yellowish ; the femora with the 

 apex broadly black, the black more extended above; tibiae 

 and tarsi black, the former broadly rufous at the base ; 

 calcaria pale. Wings hyaline, with a fulvous tinge ; nervures 

 fuscous, darker at the base ; areolet much narrowed in

 shining, sparsely haired and punctured; the front ocellus 

 surrounded by a furrow. Mesonotum shining, punctured in 

 the middle, at the base of the basal lobe almost striated.
