Fani. TINGID.E. 

 53. Phatnoma pacifica, sp.nov. 



Pale cinereous; tegmina and pronotum more or less lightly 

 clouded in part with fuscous, but there is no definite pattern, 

 and the extent and degree of inf uscation are not the same in any 

 two individuals. Sterna and abdomen also more or less fuscous. 

 First two and basal half of first segment of antennae brownish- 

 testaceous, rest dark fuscous. The form is much like that of P. 

 marmorata Champion, but the keels of the pronotum are very 

 prominent, the median extending onto and far beyond the 

 anterior lobe, and the second antero-lateral spine is more acute 

 and directed more forwards. There is one long, median, porrect 

 spine on the head anteriorly, followed by a long, submedian one 

 on each side, these being basally contiguous, subporrect and 

 apically divergent; then a long one on each side at the base, 

 basally remote, semierect, apically divergent; laterally there is 

 one long spine on each side between the eye and the antennal 

 insertion, and one on each side anterior to the antennae; nine in 

 all on the head. The underside of the head is carinately folia- 

 ceous and reticulate, the bucculae acutely prominently anteriorly. 

 The cross-keels on the discoidal and subcostal areas are not very 

 strong, though a little variable in this respect. In the costal 

 area there are 4-7 cells of subequal size in each row, though these 

 are irregular, and on the exterior margin, which is minutely 

 multisinuate, there are much larger individual cells at intervals. 

 The sternites are channelled to the base of the genital segment, 

 the labium lying along this channel, right to the end. The last 

 two or three sternites, except the last, are apically emarginate 

 angularly. Tegmina and wings extend well beyond the apex of 

 the abdomen. 



£. Last segment shaped much as in that of P marmorata, but 

 much more emarginate broadly, the genital segment being much 

 larger. 



Q. Last sternite deeply emarginate, the lateral margins a little 

 produced posteriorly, and the middle triangularly produced, so 

 that the sternite is really bisinuate.
