CLASSIFICATION OF THE ASCALAPHIDJ3. 



241 



2. I.(?) obscurus, Westwood. (Ascal. (Haplogl.) obscurus, Westw. 

 Cab. Or. Ent.) 



I can say nothing as to this species ; the type is no longer in 

 existence, or cannot be found : I am acquainted with no Asiatic 

 species with simple eyes, excepting I. decrepitus. 



G-enus Melambeotus, n. g. 



Wings long and very narrow, the inner margin longly excised at 

 the base, afterwards the inner and costal margins are nearly 

 parallel ; anterior pair appendiculate : network rather close ; 

 transverse branch of the lower cubitus confluent with the 

 postcosta in all the wings. 



Antenna short and stout, nearly straight, only about half the 

 length of the wings, without hairs at the base ; club roundly 

 capitate. 



Thorax slightly villose above, densely so on the breast. 

 Abdomen about the length of the wings, sub cylindrical, without 



appendices in the S . 

 Legs very short and strongly spinous ; spurs of the posterior 



tibiae as long as the first two tarsal joints. 

 Sab. South-west Africa. 



A remarkable genus, founded on the single species described 

 below : the wings are narrower, and the antennae shorter, than in 

 any other genus of HolopJitkalmi, and the facies altogether pecu- 

 liar. In the posterior wings the branch of the lower cubitus is 

 almost obsolete, scarcely distinguishable from the ordinary trans- 

 verse veinlets, owing to the space between the veins being so 

 greatly narrowed. 



Species. 



I. M. simia., nov. sp. Frons cinereo-pilosus. Vertex transverse fusco 

 et flavo-varius, fusco-villosus. Antennae flavae ; clava intus nigro 

 tenuiter semicincta. Thorax fusco-griseus, testaceo-varius, supra 

 sparse fusco-pilosus, infra dense cinereo-villosus ; supra maculis tri- 

 bus, quarum duse punctiformes, altera transversa, semilunata, nigris, 

 late cinereo-cinctis, vel marginatis. Pedes nigri, cinereo-pilosi, ni- 

 gro-spinosis ; tibiis ad basin obscure testaceis. Abdominis dimi- 

 dium basale cinereum, nigro-punctatum, apicale nigrum. Alae vi- 

 treae, striga subcostali e basi usque ad apicem extensa, in aream 

 poststigmaticalem dilatata, nigra, ornatae ; venis venulisque plerum- 

 que nigris, nonnullis albidis ; pterostigmate flavido, intus nigro-notato 

 (d). Long. corp. 14"'; exp. alar, antic. 32'".
