than the central lobe but not converging beyond it; eyes 

 prominent, touching the anterior pronotal angles ; antennae 

 five-jointed, first joint short, not nearly reaching apex of 

 head and scarcely seen above, second and third subequal in 

 length, each shorter than fourth or fifth, which are also sub- 

 equal in length ; pronotum about twice as broad at base as 

 median length, anterior margin very strongly concavely 

 excavated for the reception of the head, the lateral margins 

 roundly oblique and sinuate, anteriorly very obscurely den- 

 tate, posterior angles subprominent, anterior angles obtusely 

 subspinous, basal margin before scutellum truncate; scutel- 

 lum about as long as broad at base, lateral margins oblique 

 for about two-thirds from base, thence narrowed to apex ; 

 corium about as long as head and pronotum together ; mem- 

 brane slightly passing abdominal apex, with longitudinal 

 veins, some of the innermost furcate; connexivum exposed 

 from before middle of corium ; rostrum extending to the 

 fourth abdominal segment, basal joint not quite reaching 

 base of head, second extending to the posterior coxae, about 

 equal in length to third and fourth together ; abdomen 

 beneath centrally longitudinally sulcate from base to near 

 apex ; legs somewhat short and robust, posterior tibiae not 

 longer than posterior femora. 



A genus to be recognized by the compressed or flattened 

 body and the deeply concavely excavate anterior pronotal 

 margin ; it may be placed near Atelocei-a. 



Tun-ubulana plana, sp. n. 



Brownish ochraceous, thickly, coarsely, darkly punctate ; 

 central lobe (excluding apex), lateral margins of pronotum, 

 base of lateral margin to corium, a large levigate spot near 

 each basal angle of scutellum and the apex of same, and a 

 small spot on posterior disk of corium pale ochraceous ; 

 connexivum pale ochraceous, inwardly castaneous brown, the 

 latter colour narrowly reaches margin along the segmental 

 incisures; antennae black, first joint and extreme apex of 

 fifth joint reddish brown ; body beneath thickly darkly 

 punctate, but a little paler than above, lateral abdominal 

 margin as connexivum above; rostrum and legs brownish 

 ochraceous, apex of rostrum black, apices of femora distinctly 

 broadly castaneous ; membrane black, the apex ] aler.
