 Div. DALADERARIA. 

 Oyengua, n. g. 

 Allied to Dalader, A. and S., and Rormamhog aster, Karsch, but differing from 

 these genera by the following characteristics : — The basal joint of the antennse is 

 obsoletely tuberculated — much more prominently so in the immature stages of the 

 typical species described — thus showing an alliance to the genus Odontorhophala, 

 Stal. The head is very strongly emarginate between the antenniferous tubercles ; 

 the dilatation of the third joint of the antennae is very much developed outwardly, 

 but is scarcely perceptible inwardly ; the rostrum reaches the intermediate coxas ; 

 the pronotum has not the lateral angles produced in flat lobular dilatations, but 

 angulated ; the angles subacute, directed forwardly and a little upwardly ; the abdo- 

 men is strongly dilated on each side, but the dilated margins are very uneven, deeply 

 sinuated anteriorly, subquadrately produced at centre, and then regularly narrowed 

 to apex ; the femora ax'e strongly spined beneath ; the anterior trochanters have a 

 mere obsolete basal spine or tubercle ; other characters generally as in Dalader. 



Otengtja apeeta, n. sp. 

 Body above brownish-ochraceous ; the membrane, dilated margins of abdomen, 

 antennse, legs, and under-side of body, fuscous. Antennae pale fuscous, the third 

 joint with its dilatation black, and its base pale fuscous (fourth joint mutilated). 

 Body beneath speckled with black ; femora with the spines and some very obscure 

 tubercles blackish j tibiae pale fuscous, spotted or subannulated with fuscous ; tarsi 

 pale fuscous. Long., 29 mm. Max. exp. abdom., 20 mm.
