Genus HOPLOCORYPHA Stal. 



HOPLOCORYPHA PERPLEXA, new species. 



Type.— Female ; Luebo, Kongo. (D. W. Sn^'der.) [Cat. No. 14604, 

 U.S.N.M.] 



A member of the macra-galeata group, but readily separable on 

 account of the more elongate pronotum, which has the lateral carinse 

 of the caudal half of the same irregularly undulate, and by the much 

 slenderer cephalic limbs. 



Size rather large (for the genus); form considerably elongate; 

 surface rugoso-tuberculate. Head transverse, the greatest depth 

 contained nearly one and one-half times in the greatest width; 

 occipital line truncate between the juxta-ocular sulci; juxta-ocular 

 lobes rather low, obtuse, not deplanate; ocelli very small, placed in 

 an arcuate line; facial shield with the greatest depth 

 contained one and one-half times in the greatest 

 width, dorsal margin slightly arcuate, ventral mar- 

 gin subarcuate emarginate with a slight median in- 

 dentation, lateral margins moderately converging 

 dorsad, dorso-lateral angles rect-obtuse, ventro- 

 lateral angles slightly acute; eyes prominent, ovoid 

 when seen from the side; antennae very delicate, fili- 

 form, their length but little greater than the greatest 

 width of the head. Pronotum with the greatest 

 (supra-coxal) width contained about six and one- 

 half times in the length of same, the mdth at the 

 caudal margin but slightly less than the supra- 

 coxal width; collar distinctly narrower than the 

 shaft, the average width of the former slightly less 

 than a third the length of the same; cephalic mar- 

 gin strongly arcuate, slightly flattened mesad, lateral margins of shaft 

 parallel, straight to near the supra-coxal region where the margins 

 expand moderately to the obtuse-angulate lobes, narrowing caudad of 

 the same, and subparallel on the entire shaft, although very slightly 

 but regularly expanding caudad, entire lateral margins denticulate ; 

 median carina marked more or less distmctly over the entire pronotal 

 length; transverse sulcus truncate, placed very slightly in advance of ^ 

 the greatest pronotal width; surface more or less distinctly midulato- 

 lineate rugoso-tuberculate, the false lateral carinae markedly crenulato- 

 undulate; distinct usually paired tubercles placed along the median 

 carina and a semielliptical line of tubercles placed caudad on the 

 collar. Abdonoinal segments with the medio-dorsal lobe distinct, 

 largest on the second segment; supra-anal plate large, subquadrate,
