INSECTS OF SAMOA. 



28. Lygus bryani, sp. n. (Text-fig. 7). 



In the key to Lijgus by Poppius {Ami. Mus. Nat. Hung., xii, 1914) this 

 species would be associated with L. longirostris Popp., but it differs from that 

 species in several respects ; distinguished by the ecarinate vertex and lack of a 

 longitudinal groove, also by the peculiar structure of the left genital clasper. 



- Colour. — Ground colour pale yellowish tinged with greenish, dorsum 

 marked with fuscous and black ; basal half of pronotum and disc of scutellum 

 more or less blackish, pronotal disc with two yellowish rays, one each side of 



angle of cuneus blackish. Membrane dark fuscous, darker within larger 

 areole, veins yellowish. Venter rather distinctly reddish, genital segment 

 paler. Legs yellowish, femora with two fuscous annuli on apical half, tips of 

 tibia and the tarsi fuscous. 



Structure. — Length 5-2 mm., width 1-8 mm. Head : width -97 mm., 

 vertex -39 mm. ; base ecarinate except for a slight ridge at corner of eye. 

 Rostrum, length 2-77 mm., reaching upon sixth ventral segment. Antennae : 

 segment I, length -91 mm., cylindrical ; II, 2-38 mm., slender ; III, 1-6 mm. ; 

 IV, broken. Pronotum : length -95 mm., width at base 1-5 mm. ; disc finely 

 rugulose punctate, lateral margins ecarinate, slightly sulcate, calli distinctly 

 swollen, collar distinct. Scutellum distinctly convex, transversely rugulose but 

 impunctate. Clavus and inner half of corium finely rugulose punctate. Dorsum 

 thickly clothed with recumbent pale yellowish pubescence, while groups of 

 sericeous hairs produce a few lighter-coloured spots on clavus and corium.

 dorsal aspect. 



median line cutting into the 

 black, basal edge of disc pale. 

 Head yellowish, tylus and 

 sometimes frons fuscous to 

 blackish. Antennae fuscous 

 to black, basal half of first 

 and second segments more 

 or less yellowish. Hemic lytra 

 yellowish translucent, clavus 

 except more or less on outer
