218 NEW EECOEDS & SPECIES OF MALA VAX MEMBEACIDAE. 



posed on each side; posterior process short, heavy, tectiform, 

 median dorsal ridge high, tip blunt and just reaching internal 

 angles of tegmina. 



Tegmina smoky-hyaline, tinged with ferruginous; smooth in 

 central region but wrinkled in apical region ; base black, coriaceous, 

 finely punctate, sparingly pubescent; veins of central costal area 

 heavy and brown; five apical and two discoidal cells. 



Undersurface of body black, punctate and pubescent; sides of 

 abdominal segments grayish with sharp black punctures; coxae, 

 trochanters and basal half of femora black ; distal half of femora 

 lighter; tibiae and tarsi ferruginous; hind trochanters armed on 

 inner surface with strong- teeth. 



Length 4.3 mm.; width between tips of humeral angles 2.3 mm. 



Type; male (Baker's duplicate No. 9384). 



Locality : Island of Penang. 



Type in author's collection. 



This species is most interesting in that it shows a tendency 

 to a transition towards the genus Tricentrus. It very closely ap- 

 proaches Tricentrus brevicornis described above (Xo. 26) and 

 might be placed in the same genus as the latter species if the 

 suprahumeral ridges were somewhat more prominent. In general 

 facies, however, Centrotoscelus pseudocornis has more affinities to- 

 wards Cerdrotoscelus than towards Tricentrus and must be placed 

 for the present in the former genus. It may be that additional 

 forms from these two genera will show that the presence or absence 

 of suprahumeral horns will not constitute a sufficient generic charac- 

 ter as has hitherto been supposed. 



One male from the Island of Penang. 



32. Gargara projecta Funkhouser. 



One male and two females from the Island of Penang. As in 

 the type material from Singapore, the male is somewhat smaller 

 and darker than the female 'but is easily identified by the project- 

 ing head and clypens. One female bears Baker's duplicate Xo. 

 9393 and the male the duplicate Xo. -9396. The species has already 

 been reported from the Island of Penang. 1 



33. Gargara attenuata Funkhouser.

 XXII: 3, p. 236, 4, Fig. 4. 

 Two females from the Island of Penang and one male and one 

 female from Sandakan. Borneo. One female from the Island of 

 Penang bears Baker's duplicate Xo. 9392. The male from Borneo 

 is numbered 9832 and the female 9831. This species was described 

 from Banguey ; the specimens here recorded agree in all respects 

 with the type material with which they have been compared.
