closely applied to the head, in the small size of the basal projection of the tarsal 

 claws, the presence of a comb on the under side of the last mid and hind tarsal 

 segment, and in the shortness of the prosternura. On the other hand, its short legs 

 and the dorsal combs are Old- World characters. The new genus, therefore, forms 

 a kind of connecting link between the Eastern and Western Polyctenids. 

 The tibiae are very remarkable for having only a single pseudo-joint.

A broad and very hairy species, of which the Entomological Research Com- 

 mittee (Tropical Africa), only received one specimen, an adult female, and wiiich we 

 have great pleasure in naming after the distinguished Hemipterist Dr. Horvath. 

 The clipens is about five times as broad as it is long, its diameter being shorter in 

 the centre than at the sides. The hiud margin is more strongly arched in the centre 

 than the anterior margin and bears laterally a row of ten bristles. The lateral 

 bristles on the under side of the clipeus difl:er remarkably from those of the other 

 Polyctenids, the three central ones being modified into short stout spines (PI. XIV. 

 fig. 12), and the last proximally incrassate and distally thin, while the first is 

 represented by several minute hairs. 



The head exclusive of the clipeus is shorter than broad (proportions 5 : 7), and 

 its upper surface, with the exception of the anterior portion of the central area, is very 

 densely covered with short and stout but very sharply pointed bristles. The oblique 

 sutures are very distinct and nearly straight. They are accompanied on the outer 

 side by a row of short bristles, laterally to which there is a naked stripe. The 

 spines of the comb at the posterior margin are longer than the bristles placed 

 nearest to them, and twice as long as the spines of the pronotal comb. 



The gular comb nearly reaches to the basal angles, and contains 59 teeth 

 on the two sides together. The central gap is as broad as the distance from the 

 tip of the first spine to that of the eighth. Laterally to the comb there is a row of 

 bristles. Close behind the comb six small hairs are placed on the right side of the 

 central groove and four on the other. Farther back the edge of the groove bears 

 six very small hairs on each side, and at and near the basal angles of the head there 

 are three or four short bristles resembling the bristles of the upper surface. The 

 median portion of the hind margin is less produced than is usual in Polyctenids, 

 and also much broader, being nearly twice the width of each lateral portion 

 (12 : ~ ). The hind margin is distinctly rounded between the coudyli and the 

 basal angles. 



The proboscis consists of four segments, of which the last is the most slender, 

 being hardly wider in the centre than at the base. The projwrtional lengths of the 

 second to fourth segments are : 14, 8, 17. The second segment is open at the base 

 on the anterior side, and the third and fourth segments only appear to have a 

 median groove. The small size of the third segment is noteworthy. The bristles 

 of the second and third segments are rather long. 



The antennae, which reach to the basal angles of the head, are quite difi'erent
