110 DescriiJtive Catalogue [1896. 



probably be better to sink the three genera in synonymy and con- 

 sider them as mere sections of Drojnica. 



Gen. DEOMICA, Dej. 



Section A. — Cosmema. 

 Section B. — Myrmecopteea. 

 Section C— Dromica. 



Section A. — (Cosmema.) 



A., p. 82. Elytra with three oblong supra-marginal spots 

 on each side, the posterior outer angle produced in a small 

 spine in the female, the four median joints of antennae sub- 

 compressed dolosa. 



D., p. 83. Elytra pitted and with a white marginal band 

 sending past the middle a short slanting spur. 



Dorsal part depressed, sutural part almost transversely 

 plicate, a bright metallic sheen on each side of the suture . . niiranda. 



Dorsal part not depressed, sutural part irregularly punctured, 

 no sheen along the suture, which is highly carinate aspera. 



E. Elytra with the anterior part deeply pitted, each with a 



narrow apical supra-marginal band transitoria. 



F. Elytra with a dorsal, round, white spot in the posterior 

 part, a small humeral lateral band, and another one running 



from the median part to the outer apical angle gloriosa. 



Cosmema dolosa, Per., 

 Trans. Entom. Soc. Lond., 1894, p. 452. 



Dark bronze, with a greenish tinge ; the lateral parts of the elytra 

 cyaneous ; under side and legs dark greenish blue, tibiae rufescent ; 

 antennas subcompressed and slightly foliate ; head finely strigose 

 diagonally; labrum black, with the apical part somewhat yellowish 

 in the male, totally black in the female ; prothorax narrow, cylin- 

 drical, constricted behind, finely transversely plicate; elytra elongated, 

 covered with deep, closely set, moderately broad punctures, convex, 

 with the sutural part ending in two short spines on each side, as in 

 C. lejncla, Bohem., but much shorter, and having on each side three 

 ovate, supra-marginal white spots, the first one humeral and very 

 small, the median one a little elongated, and the posterior one ovate. 

 Length 10 mm. ; width 3 mm. 



This species, owing to the tendency of the antennas to become 

 compressed and subfoliate, connects Cosmema with Myrmecoptera ; 

 like C. lepicla, it has two spines on each side of the suture, but these 

 spines are not so much developed; the supra-marginal w^hite markings 

 are not unlike those of C. elegantula, Bohem., but in C. dolosa the 

 posterior one is a round or ovate patch, not a w^hite line or band. 



Hah. Zambezia (Salisbury).
