Tutuila :— 1,100-1,200 ft., 1 specimen, iv.l918 (Kellers); Afono Trail: 

 1 specimen, 25.ix.1923 (Swezey and Wilder) ; Pago Pago : 1 specimen, 2.xii.l924. 



Only known to occm: in Samoa. The genus is based on a Philippine species 

 and Kirkaldy has described a third species native to Fiji. 



Bryanella,* gen. n. 



Head and pronotmn strongly deflexed, head slightly exserted, a little 

 shorter than wide across eyes (22 : 25) ; eyes prominent but not stylate ; vertex 

 three times as wide as diameter of an eye (33 : 11) ; ocelli placed posterior to a 

 line drawn between posterior margins of eyes, further from one another than 

 from eyes (8:5); base of vertex between the ocelli with a short longitudinal, 

 rather deep pit or depression ; lateral margins of juga distinctly carinate 

 forming definite supra-antennal ridges ; antenniferous tubercles moderately 

 prominent (seen from above), bucculae very short semicircular, not extending 

 as far as level of insertion of antennae ; rostrum extending to hind coxae, first 

 segment reaching level of posterior margin of eyes ; antennae very long and 

 slender about as long as the total length of insect including membrane, fourth 

 segment distinctly thickened. Pronotum with the anterior collar very distinct 

 somewhat swollen in middle, rather less than one-half as long as the anterior 

 lobe (6 : 14) which is indistinctly separated from posterior lobe ; anterior lobe 

 two-fifths the length of posterior lobe (14 : 35), its lateral margins convex not 

 carinate ; posterior lobe more than twice as wide posteriorly as anterior collar 

 (94 : 40) with its lateral margins straight, not carinate except posteriorly just 

 above rounded humeral angle where there is a short very distinct ridge abruptly 

 terminated posteriorly to form a distinct angle or tooth ; posterior margin 

 almost straight. Scutellum longer than broad at base. Hemielytra with 

 apical three-quarters of costal margin distinctly refiexed, and rather sinuate. 

 Legs slender, femora not incrassate, unarmed ; posterior tibiae with external 

 row of distinct bristles. 



Genotype : — Bryanella longicornis, sp. n. 



This genus seems to be more or less intermediate between the Myodochini 

 and Rhyparochromini. In the short bucculae, short indistinctly delimited 

 anterior pronotal lobe, long antennae and bristled hind femora the genus 

 approaches the Rhyparochrojiiini, but in the Avell-developed anterior collar and
