Nauphoeta; posterior femora armed on the posterior margin beneath 

 with 1 — 3 spines. Posterior raetatarsi shorter than the succee- 

 ding joints. 



Pronauphoeta nigra sp. n. 



cf. Very dark castaneous. Head piceous with ocelli and 

 niouth-parts testaceous. Antennae fuscous, equal in length to the 

 body. Frons depressed, concave ; eyes not approximated on Vertex. 

 Pronotum faintly punctate, anterior margins on either side of the 

 head testaceo-hyaline. Tegmina seriate-punctate at base, reticu- 

 late at apex. Wings with the veins and marginal area castaneous, 

 ulnar vein with 13 incomplete and 3 complete rami. Supra-anal 

 lamina snb-quadrate, apex scarcely incised, not exceeding the sub- 

 genital lamina which is sub-transverse. Cerci short, apical Joint 

 enlarged. Femora and coxae testaceous , tibiae and tarsi testa- 

 ceous ; formula of apical spines y, y, J; Hind-femora with 1 — 2 

 spines on the posterior margin beneath. 



Total length 21 mm; length of body 15 mm; length of 

 tegmina 17 mm; pronotum 5x6,2 mm. 



Kamerun (Conradt) (Deutsch. Ent. Nat.-Mus., type). 



The other species of the genus are Panchlora smaragdina Br. 

 (syn. P. vitellina Gerst.) and P. adusta Ger st. The genus is inter- 

 mediate between Panchlora and Nauphoeta, for the species that 

 I include in it have the pronotum and the subgenital lamina of 

 the male as in Panchlora but the armature of the femora as in 

 Nauphoeta and consequently I consider it advisable to separate the 

 species exhibiting these characters from Panchlora. Three true 

 species of Panchlora are found in Africa , viz. P. stolata Borg, 

 P. camerunensis Borg and P. vosseleri Shelf. 



Sub-fam. Oxyhaloinae. 



Areolaria sumatrana sp. n. 



?. Head rufous (antennae missing). Pronotum transversely 

 sub-quadrate, punctate, rufous, the lateral and posterior margins 

 testaceo-hyaline. Tegmina piceous, seriate-punctate, marginal area 

 and discoidal sectors testaceous. Wings castaneous , mediastinal 

 vein 3-ramose, 12 costals, these with the rami of the mediastinal 

 vein incrassated, medio-discal area nearly twice as broad as medio- 

 ulnar, ulnar vein bifurcate, 1^' axillary vein 4-ramose, triangulär 

 apical area large. Abdomen above and beneath and legs orange-rufous. 



Total length 8,2 mm ; length of tegmina 6,6 mm ; pronotum 

 2x2,8 mm. 



Sumatra (Deutsch. Ent. Nat.-Mus., type). 



Allied to A. signata mihi but differently coloured.
