HOPLOCORYPHA BOVIFORMIS, new species. 



Type. — Male; St. Paul de Loanda, Angola. [Cat. No. 14605, 

 U.S.N.M.] 



Allied to H. horomensis Brancsik from Zambesia and H. hispina 

 Saussure and Zehntner from Madagascar, differing from both in the 

 extremely slender form of the pronotum and the spinif orm character 

 of the juxta-ocular lobes. From hispina it also appears to differ in 

 the smaller size. 



Size rather small; form elongate; surface closely and finely tuber- 

 culate. Head with the greatest depth contained one and one-half 

 times in the gi-eatest width; occipital outline truncate between the 

 juxta-ocular sulci, juxta-ocular lobes rectangu- 

 late with the apices acute, mammiform, diverg- 

 ing, the lobes very slightly depressed; ocelli 

 rather small, placed in an arcuate line; facial 

 shield strongly transverse, dorsal margin trun- 

 cate mesad, obliquely arcuato-emarginate lat- 

 erad, ventral margin slightly arcuato-emargi- 

 nate, lateral portions very narrow; antennae 

 slightly shorter than half of the pronotal length, 

 simple; eyes very prominent, subglobose, ovoid 

 in form when seen from the side. Pronotum. 

 slender, elongate, the gi^eatest (supra-coxal) 

 width contained nearly six times in the length; 

 collar markedly tapering cephalad from the 

 supra-coxal angles to the middle of the collar, 

 thence subequal cephalad to the strongly 

 rounded cephalic extremity, supra-coxal angles 

 very slight but distinct; shaft slightly tapering 

 caudad to the caudal third, thence subequal to 

 the truncate caudal margin; lateral margins of 

 the whole pronotum denticulate, a slight but 

 distinct median scarina present throughout 

 the pronotal length, transverse sulcus U shaped, not severing the 

 median carina; paired supplementary carinas on the shaft dis- 

 tinctly concavo-arcuate, closely and finely tuberculate, the tuber- 

 culations of the other (more lateral) portions of the shaft and of the 

 collar arranged in linear fashion. Abdomen without marked medio- 

 dorsal lobes on the caudal margin of the segments; supra-anal 

 plate with the proximal width slightly greater than the length, 

 lateral margins arcuato-convergent caudad, apical margin bisarcuate; 

 cerci but slightly surpassing the supra-anal plate, deplanate, moder- 

 ately broad, apex acute; subgenital plate with, the distal half of the 

 lateral margins converging distad, the apical extremity very narrow,
