64 My. Jaraes Edwards" Siinojjsis of 



than crown. Sciitellmn about twice as long as pronotuni. Elytra 

 whitish hyaline, slightly widened towards their rounded apex ; on 

 the membrane a black or dark brown streak, continued to the base 

 of the elj'tron as a wide ill-defined brown stripe, which is sometimes 

 very faint, but always discernible on holding the elytron up to the 

 light. Abdoixien above blackish, with a narrow pale dorsal line. 

 Styles (PL II., fig. 14) oblong, parallel, very distinctly flattened 

 vertically, suddenly acuminate at about the apical third. Insect 

 generally macropteroiis. Length, 3 — 4 mm. 



Not uncommon. In the brachypterous form the elytra 

 are sublanceolate, but specimens in this state are easily 

 distinguished from guttida by their superior size.

At first sight this species much resembles a very small pale 

 example of the foregoing, but upon examination it proves to be 

 abundantly structurally distinct. Crown, pronotum, and scutelhmi 

 pale yellow ; the sides of the two latter, although sometimes 

 slightly darker than the disc, do not appear to develop the dark 

 stripe so conspicuous in guttulifera, at least such is not the case in 

 the twenty examples I have examined. Elytra not widened to- 

 wards their sublanceolate apex, the dark marking on the membrane 

 rarely more than a small subtriangular black spot. Styles (PL II., 

 fig. 13) curved, subparallel, scarcely perceptibly flattened vertically, 

 gradually acimiinate fi'om the base. Length, 2^ — 2^1^ mm.

 macropterous.
