The brighter coloured pubescence forms a conspicuous 

 vertical stripe on each side of the head from, an antenna to 

 the tip; occupies the space between the four discal tubercles of 

 the pronotum, and is continued almost to its base; is very 

 irregularly disposed in spots and patches on the elytra, of 

 which it occupies about one-third (or less) of the surface; 

 forms a conspicuous round spot on each side of the meta- 

 sternum; a spot on each side of the four basal segments of 

 abdomen (diminishing in size posteriorly) ; one on each of the 

 four hind femora, and a feeble one on each of the front 

 tibiae. The tubercles on each side of the disc of the pronotum 

 aFe fairly close together, but not conjoined as on others of 

 the genus, and the swelling on each side is much more obtuse 

 than on those species. The curved row of tubercles on each 

 elytron commences, in the middle of the base, with a small 

 subcorneal one, and ends with a small round one at the basal 

 fourth ; on the right side it consists of six and on the left of 

 five tubercles; the humeral elevations are so small that they 

 should be regarded as granules. 



The typical species of the genus, umbrosa, is unknown to 

 me ; the present species differs from its description in its very 

 different clothing, and isolated prothoracic tubercles; inter- 

 coxalis in having a conspicuous projection between the front 

 coxae as well as a somewhat smaller one between the middle 

 pair; setipennis has a conspicuous medio-basal tubercle on the 

 pro thorax, the elytra with tubercles not as described and with 

 numerous scattered white setae or hairs; and guttatiis has 

 four conspicuous white spots on the elytra. These may be 

 tabulated as follows : — 



With a conspicuous projection between front coxae intercoxalis 

 Without such. 



Pronotum without a median tubercle towards 



base maculiventris 



Pronotum with such. 



Elytra with four conspicuous white spots ... guttatus 

 Without such setipennis 



Brachaciptera, n. g. 

 Head short; labrum membranous. Eyes rather large, 

 reniform, widely separated, semicircularly notched, rather 

 finely faceted. Antennae long and thin, not spinose. Palpi 

 rather small. Prothorax slightly longer than wide, sides 

 obtusely armed, incurved near apex and base. Scutellum 

 rather large. Elytra at base much wider than prothorax, 

 suddenly and strongly narrowed from base to about middle,, 

 and then thin and almost parallel-sided to apex. Metaster- 

 num prominent. Adbomen considerably below level of meta- 

 sternum, rather thin, not covered by elytra, intercoxal process
