A CATALOGUE OF THE HEMIPTERA OF FIJI, 



sterna and pleura dark fuscous, anterior margin and middle of 



collar, and hind margin and 



middle of posterior lobe, 

 ochreous. Second segment of 

 antennae rather longer in pro- 

 portion. Eyes smaller and 



Fig.l.-Enicocephalus corticicola; less prominent. Anterior 

 tegmen. lobe of pronotum longer and 



wider in proportion. Length 6^ mill. 



Viti Levu (Muir's No. 155), under the bark of an old fungus- 

 filled tree. 



It is possible that this and the preceding are the two sexes of 

 one species, but no one has succeeded as yet in differentiating 

 these forms sexually. 



The nymph of the last instar (of one species or the other) is 

 very similar to the adult, but the antennal segments are all stout, 

 the fourth segment much the longest. Anterior and posterior 

 lobes of the pronotum equally wide, much wider than the collar. 

 Fore claws a little less connate. 



Fam. REDUVIIDiE. 



65. Polytoxus sp. 1 ? 



Rewa (February and November; Muir). 



66. Oncocephalus pacificus, sp.nov. 



Very closely allied to the Mascarene 0. angulatus Reuter, but 

 the eye (<£) occupies the whole height of the head, and the pro- 

 sternal spines are more strongly uncinate. First segment of 

 antennae pale brownish-yellowish, a little infuscate beneath 

 apically, second segment yellowish. Sterna and pleura yellowish- 

 brown, irregularly striped and marked with fuscous. Sternites 

 yellowish-brown, with a broad sublateral and a narrow submedian 

 indeterminate dark fuscous stripe down each half. Pleurites 

 brownish-yellow, a fuscous spot on apical margins of each, 

 exteriorly. Fore femora less incrassate, with ten spines. Hind 

 femora strongly adspersed with blackish-fuscous, darker and 

 closer apically, base and trochanters pale. Prosternal spines
