MUTTLLA. 283 



with a gradually rounded slope to the apex ; covered with long pale hair ; the basal 

 area elongate, curved inwardly before the apex ; the apical tubercle shining, not very 

 distinct. The basal segment of the abdomen shining, and with some large, widely 

 separated punctures and some longish hair ; the extreme apex ferruginous and fringed 

 with rufous hair. The second segment shining, the sides with some shallow scattered 

 punctures ; the apex, as also the other segments, fringed with rufous hair ; the other 

 segments indistinctly punctured at the base. The pygidium punctured in the middle, 

 covered with rufous hair ; down the sides is a broad keel, which becomes more distinct 

 and wider towards the apex ; and there is a still broader central keel, the apex of which 

 is bluntly rounded. The basal ventral segment is keeled down the centre and slightly 

 depressed ; the sides with some large punctures. The second segment with some fine 

 scattered punctures, and with a transverse row of larger ones before the apex. The 

 other segments bear some fine punctures and a sparse fringe of fulvous hair. The base 

 of the hypopygium is raised, and triangular at the apex of the raised part ; the apex is 

 depressed and in the middle projects into a triangle. The radial cellule is wide and 

 longer than the first cubital ; the basal abscissa of the radius is straight and oblique, 

 the apical abscissa curved, and slightly elbowed at the top. The second cubital cellule 

 is narrower at the top than the space bounded by the first transverse cubital and the 

 first recurrent nervures ; the third cubital cellule at the top is as wide as the space 

 bounded by the second transverse cubital and the second recurrent nervures ; the third 

 transverse cubital nervure bulges out in the middle. The recurrent nervures are 

 recurved about the same distance beyond the middle of the cellules. The transverse 

 median nervure is received before the basal.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



Head coarsely punctured, densely covered all over with glistening white hair; the 

 clypeus with an oblique slope to the apex, which is transverse, the sides oblique ; the 

 mandibles piceous at the subapical tooth. The eyes large, the head moderately deve- 

 loped behind them, and roundly and rather sharply narrowed ; the incision wide, semi- 

 oblique. The scape of the antennae punctured, moderately covered with white hair ; 

 the flao-ellum with a whitish pile ; the third and fourth joints subequal. The pronotum 

 rather strongly punctured ; the base with long pale hairs ; the apex with a dense band 

 of white pubescence. The mesonotum shining, the punctures large and elongate; 

 there are two furrows and also a smooth shallow keel down the sides; the hair is 

 sparse and blackish. The tegulse large, shining, dilated behind ; the apex on the inner 

 side thickly covered with greyish hair. The scutellum flattish, not much raised oier 

 the mesonotum, covered with large, distinctly separated punctures, the apex with long
