Cue ?. 



The npperside is clothed with long black hair.s. The same covering is found 

 in )ii(/rosii/»afa and ?iif/r(ijji!os(i, hnt since the hairs break off rather easily, one meets 

 with iiulividnals whicli are covered witii very short hairs onl}-. 



Macrochia gen. nov. 



c? ? . Allied to Synhomelix and Couie-^tlies, tlie midtibia being excised beyond 

 middle as in these genera. Prosternum with a liigh conical tubercle ; mesosteriium 

 declivous, with an obtuse tubercle, or not tuberculate. 



Typus : texata (1858) Chevr. 



Here belong, besides (I'xata and the new species, decussata and liyafa. 



87. Macrochia lutosa spec. nov. 



?. Close to M. tiwata, but the elytra decidedly longer, the scutellnm short and 

 truncate, and the pale ]iubosccuce dee])er clay-colour and more extended. The black 

 occipital patch of texata represented in lutosa by a small spot at eye and an 

 irregular spot before pronotum. Scutellnm all claj'-colour. The black areas of 

 the elvtra reduced, the oblique band-like patch narrower and the basal black area 

 obviously smaller than in texata. 



Length, 26 mm. ; elytra, 18 mm. ; breadth, 8 mm. 



Hab. Benito, French Congo. 



One ?. 



Coniesthes (1893) Kolbe. 



Here belong Pavhijstola minica (1800) Bates, and P. tibialis (1894) Jord. 

 Conie-stlies nigrojasciata (1893) Kolbe is the same as Pach/stola fallax (1894) 

 Lameere, of which the type is in the Tring Museum (ex coll. Alluaud), and also the 

 same as Trayocepkala (?) signaticoniis (1855) Chevr., which is left in Tragoccphala 

 in the Munich Catalogue, and of which the type is in the British Museum. 



Cyclotaenia gen. nov. 



? . Allied to Synhomelix and Macrochia. Frons broader tlian long. Antennal 

 tubercles short and widely separate. Lower lobe of eye smaller than in the allied 

 genera, not higher than broad. Distance of upper lobe from the mesial sulcus of 

 the head twice the width of the upper lobe. Mandible smooth, punctured proximally, 

 but not rugate. Labrnm large, strongly rounded at sides and apex, sinuate in 

 middle. Antenna as in the allies, scape shorter, stouter, and grannlose at end. 

 Prothorax with slender, acute, median side-tubercle ; two ai)ical transverse sulci, 

 the first not reaching upperside, the second indistinct only in middle ; no tubercles 

 on disc. Elytra broad, evenly convex, coarsely granulate-foveolate at base. Pro- 

 sternum evenly rounded, with a short conical tubercle in middle ; mesosternum 

 declivous, with a higher conical tubercle. Midtibia grooved.
