 to the middle, where this colour ascends dorsally, reddish brown ; 3 to 

 6 light reddish brown, marked with dark bronzy green ; a broad 

 terminal ring, somewhat less than the apical fourth ; a dorsal band, 

 broad at the beginning at about one-fifth of the segment's length from 

 the anterior margin, gradually narrowing to a somewhat diffuse con- 

 fluence with the terminal ring ; 7 black, a narrow basal brownish ring, 

 dorsally interrupted ; 8-10 black, 9-10 with thin whitish pruinosity.

Abd. 38 + 1-5, hdw. 27,^. < 2 mm. 



CHLOROLESTBS UMBRATA (Se'lys, 1862). 



Mus. Brussels (formerly de Selys' Collection); 1 , being a type 

 of the original description, as testified by the following labels : 

 (Chlorohstes umbratum, H. <^ [in Selys' hand]/ Schneider Charpentier. 

 (id.) I L. umbrata . . . Cap. b. sp. [in Hagen's hand] Prom. b. 

 sp. / Mus. Berol.) Brit. Museum : 1 $ , bearing an old round label 

 C[ape of] G[ood] H[ope] 42 70. 



Both specimens belong to the same species, which is not otherwise 

 represented in our series and is evidently a very distinct species. In 

 the Selysiau specimen the abdominal segments 7-10 are lost (replaced 

 by the corresponding segments of AUocnemis leucosticta) ; in the 

 British Museum specimen the colours are not in good condition and 

 the left pair of wings is lost. 



cf . Labium dull brown. Occiput black. Labrum, anteclypeus, 

 geuae, base of mandibles and frons to the base of antennae dull 

 reddish brown (discoloured and probably lighter in well-preserved 

 specimens) ; dorsal side of head otherwise black, with an appearance of 

 rather large reddish brown (as above) postocular spots. Prothorax 

 metallic green, sides narrowly yellowish. Thoracic dorsum brilliant 

 metallic green, this colour occupying also part of the sides, the mes- 

 epiuierou entirely ; a large cuneiform stripe on the rnetepisternum, 

 the entire breadth of the sclerite at the dorsal end, a point just above 

 the metastigma ; on the metepimeron a small spot near dorsal end of 

 second lateral siiture, narrowly joined to metepisternal black stripe. 

 Light yellowish brown or orange : a very narrow line on humeral 

 suture stopping a little short of the dorsal end ; a small round spot 

 m the antero-dorsal angle of mesepimeron ; ventral half of nietepi-
