23. Lygus samoanus, sp. n. 



Allied to L. ventralis Popp., but differs from this and related species by the 

 longer first antennal segment ; length of segment I slightly exceeding width of 

 head across eyes. 



Colour. — Ground colour pale greenish-yellow, basal angles of pronotum 

 and extending along base of propleura, clavus, and inner apical angles of 

 corium, reddish to brownish-black ; antennae reddish to fuscous with paler at 

 base of first and second segments ; tibiae and hind femora reddish in darker 

 coloured specimens, tibial spines brownish and without spots at base ; membrane 

 and veins uniformly dark fuscous.

 while only 1-52 mm. across tip of clavus. Head : width -99 mm., vertex 

 •39 mm. ; position vertical, vertex ecarinate, base of tylus confluent with frons, 

 lora prominent. Rostrum, length 1-73 mm,, only reaching upon middle coxae. 

 Antennae : segment I, length 1-08 mm,, cylindrical, finely pubescent ; II, 

 2-51 mm., slender ; III, broken. Pronotum : length 1-05 mm., width at base 

 1-65 mm. ; disc very minutely punctate, calli evident as slight transverse 

 swellings. Dorsum clothed with fine, short, pale yellowish pubescence ; 

 scutellum and clavus finely rugulose but scarcely punctate. Hemielytra wider
