SI 
l)i,filribution.—Chi\i. [Buenos Ayres. Patagonia. Coloinl)ia.] 
Blackish brown; apical margins of connexival segments 
broadly pale; membrane maculated, pale along tlie veins. 
Head slightly longer than broad (24 to 22), longer than pronotnm (24 to 
20); tyins comparatively large, thick, sides nearly i)arallel; impressions of 
vertex short, broad, rather deep, widely se])arated, parallel, connected pos- 
teriorly; ])reocnlar tubercles distinct, obtuse; antenniferous spines short, 
moderately stout, slightly divergent, without lateral tooth; postocular tuber- 
cles rather prominent, rounded; antennae (tig. 4()c) moderately stout, shorter 
than head and pronotum together (3.S to 44), the first segment reaching 
scarcely to middle of tylus, second and third very distinctly flattened, the 
second narrowed only at extreme base and as long as distance between eyes; 
rostrum reaching about to middle of mesosternum. Pronotum (fig. 40(1) 
moderately convex, the lateral margins rather l)roadly exinxnded and dis- 
tinctly reflexed, very finely granulate, variably sinuate anteriorly; carinae 
narrow, distinctly elevated. Scutelhmi much longer than pronotum (30 to 
20), triangular; sides strongly elevated, variably arcuate; apex very nar- 
rowly rounded; discal elevation rather small and high; base dejiressed. Hemi- 
elytra (9) extending almost or (juite to genital lobes, corium over base of

9 (fig. 40a). Posterior margin of dorsal genital segment bisinuate, emar- 
ginate at middle; abdomen narrowlj^ oval, l)ul little broader tlian hemielytra. 
Length, 5 to 5.7 mm. 
Type spceiineiis (Cdiile) not loeated. 
There are examples of this South American species in the 
I'hler collection (U. S. N. M.), from Cdiile, and it is reported by 
Stal and others from various parts of the continent. It is readily 
di,sting;uished from liuiuhris ])y the antennal structure and geni- 
ftdic traits. 1 have not seen specimens of this species other than 
those mentioned above, but its characters are so distinctive that 
1 think there can be no doubt regarding the identification.
