290 Mr. P. Cameron on neio 



Apex of clypeus transverse ; the labrum slightly projecting 

 laterally and to a less extent in the centre ; it is fringed with 

 long bright rufous hair. Mandibles and palpi black. Thorax 

 opaque, alutaceous, densely covered with long black hair ; 

 the pleurse obscurely punctured and with a distinct oblique 

 furrow near the middle. The apex of the median segment is 

 bare, smooth, and shining. Wings fulvous hyaline, the apex 

 with the fulvous tinge less well marked and with a violaceous 

 tinge. The stigma and costa are black; the nervures are 

 testaceous ; the second cubital cellule is distinctly shorter 

 than the third above and below ; the third transverse cubital 

 nervure has the upper half straight and oblique, the lower is 

 not so oblique and broadly rounded. Legs rufo-testaceous, 

 the tarsi paler, the coxse, trochanters, and basal half of the 

 femora black. Abdomen smooth and shining. 



A distinct species. Characteristic is the long, dense, black 

 hair on the head and thorax. 



Salius Frederici, sp. n. 



Black; the antennse (except at the base and apex) fulvous; 

 the tibiae (except at the apex and the hinder tarsi) rufous ; 

 the apices of the joints of the hinder tarsi black; the wings 

 flavo-hyaline, the base of the anterior dark smoky to the 

 transverse basal nervure, the hinder pair with the basal half 

 dark fuscous, the apical yellow, d . 



Long. 23 mm. 



Claws "with one stout tooth. Antennae as long as the body, 

 distinctly tapering towards the apex.. Head black, sparsely 

 covered with long black hair ; the inner orbits narrowly, the 

 face, clypeus, and labrum dark rufo-testaceous. A distinct, 

 deep, narrow^ furrow extends from the ocelli to the middle of 

 the front. Clypeus roundly convex ; its middle at the apex 

 transverse, the sides rounded. Mandibles black, the upper 

 part testaceous. The head is obliquely narrowed behind the 

 eyes and is well developed there ; there is a testaceous line 

 on the outer orbits above. Thorax opaque, sparsely covered 

 with long black hair; the median segment is longish, has a 

 gradually rounded slope, and is obscurely transversely striated. 

 Wings yellowish hyaline ; the base above is dark fuscous, 

 with a violaceous cloud to the transverse basal nervure, below 

 the cloud extends to the submedian nervure ; the second and 

 third cubital cellules are almost equal in length at the top 

 and bottom ; the third transverse cubital nervure has the
