the longest of the two, is comma- shaped and coalesces along the 

 margin with an apical marginal line, while the inner one is more or 

 less ovate and moderately close to the suture ; under side and legs 

 cyaneous ; lateral part of abdomen not thickly covered with hairs ; 

 anal segment rufescent. Length 12-13 mm. ; width 4 J mm. 



Hab. Zambezia (Salisbury). 



In one of my examples the anterior yellow patch on the elytra has 

 disappeared, and the external posterior patch does not quite coalesce 

 with the apical yellow margin. 



The livery of this species is very different from that of any other 

 South African Cicindela ; the facies is also slightly dissimilar. 



Sub-Gen. PEODOTES. 

 Prodotes mimula. 



Shape, size, and colouring of P. fatidica ; the labrum is more 

 broadly infuscate at the tip, the head and prothorax are similar, the 

 elytra are a little more ampliate and not serrulate behind, black, 

 mottled with small round velvety patches ; the diagonal dorsal band 

 is very narrow, extends from the shoulder to two-thirds of the length, 

 and emits in the median part a slender ramus which reaches near to 

 the outer margin, the two juxta-sutural yellow spots on each side of 

 the suture are very small, and the supra-marginal posterior band is 

 very narrow and is surmounted by a narrow crescent-shaped patch; 

 under side and legs cyaneous. Length 15-16 mm. ; width 5-6 mm.

Gen. COSMEMA, 



Catal., p. 81. 



My arrangement of Myrmecoptera, vid. Catal., p. 61, will be im- 

 proved by including in this genus Dromica clathrata, D. pseudo- 

 clathrata and D. grandis, leaving in Dromica proper only such species 

 as have filiform antennae and quadrate prothorax with two protu- 

 berances on each side of the disk ; type D. sculpturata and D. 

 tuberculata. 



Strictly speaking, the genus Dromica was created for D. coarctata, 

 which is a Cosmema, and I should have felt inclined to restrict to 

 Dromica all the species I have placed in Cosmema, had not Dejean 

 himself in his ' Supplement au Species General des Coleopteres,' 

 vol. V. pp. 269-270, included in Dromica another Cosmema, C. 

 vittata, as well as Dromica tuhercidata.* 



The species included in Cosmema are more closely allied to many 

 of the Myrmecoptera of the slender type than to Dromica, and it will
