212 Mr. W. L. Distant on the 



part of the discal portion of third segment. There is also 

 a faint transverse linear tuberculous ridge on disc of basal 

 margin of the second segment. The posterior femora are 

 gradually thickened, curved at base, unarmed, faintly 

 tuberculous along inner margin, about as long as posterior 

 tibife and tarsi together. The posterior tibite are dilated 

 on each side, outwardly from base to about half their 

 length, inwardly gradually widening from base and apex 

 to a broad acute tooth about the middle. Intermediate 

 femora slightly dilated beneath near apex with a strong 

 subapical spine. Coxfe gradually widened apart ; anterior 

 close together, intermediate much wider apart but less so 

 than posterior. 



Long. 28 mill. ; exp. pronot. ang. 1 1 mill. ; exp. body 

 at base of cor. 8 mill. 



Antananarivo. 



I possess one small S , measuring only 25 mill., in which 

 the tuberculous ridge on disc of basal margin of second 

 segment is almost obsolete. 



This species cannot well be confused with M. tuber- 

 culosa, Sign., the only other African species to which the 

 genus is now restricted. 



$ . Antennas relatively shorter and brighter castaneous, 

 pronotal angles somewhat less prominently produced, pos- 

 terior femora very slightly thickened and posterior tibite 

 not toothed internally. 



Mictis expansa, n. sp. (PI. V. figs. 1, 1«.) 



$ . Above purplish-brown. Head and anterior margin 

 of pronotum pitchy, clothed with ochreous pubescence. 

 Antenna bright castaneous, apical joint excepting base 

 black. First joint longest, 2nd a little longer than 3rd, 

 4th and 2nd subequal. Pronotum rugose and granulate, 

 the lateral angles much produced into acute processes, 

 directed somewhat upwards and forwards with the 

 margins faintly crenulated. Anterior lateral angles much 

 more distinctly crenulated. Scutellum trans vei'sely and 

 coarsely wrinkled. Clavus much streaked with pitchy, in 

 some specimens concolorous. Corium thickly and finely 

 punctate. Membrane brassy-black. Abdomen above 

 black, Avith two luteous spots on base of fifth segment. 

 Body beneath concolorous (in other specimens somewhat 

 darker). Coxfe, trochanters, tibias and apices of femora 

 somewhat pitchy; tarsi luteous.
