HEMIPTERA— HETEROPTERA.

anterior lateral angles obtuse but slightly prominent, basal margin in front of 

 scutellum truncate ; lateral margins more or less straight, somewhat indented 

 in middle between anterior and posterior lobes ; posterior angles broadly rounded 

 not wider than costal margins of hemielytra ; disc of anterior lobe with a pair 

 of flattened strongly rugose circular prominences and a short longitudinal rugose 

 ridge on each side, lateral margins carinate. Scutellum triangular, with margins 

 slightly concave, slightly shorter than broad at base (20 : 23), lateral margins 

 and base, narrowly ridged, disc with a broad distinct, percurrent median ridge. 

 Hemielytra extending to eighth abdominal segment ; corium reaching distinctly 

 beyond the apex of the scutellum, its apical margin convex ; basal costal lobe, 

 narrow, extending slightly beyond connexivum in an obtuse tooth level with 

 the middle of the scutellum ; membrane with obscure semi-obsolete reticulations. 

 Second abdominal spiracle on lateral edge of connexivum, the rest ventral, that 

 of the seventh placed close to lateral margin ; posterior margin of sixth ventrite 

 deeply emarginate in the form of a parabola ; seventh ventrite very long ; 

 processes of eighth and the ninth ventrite (pygophor) little prominent. 



Length, 4 mm. Breadth across humeral angles, 1-5 mm.

Readily distinguished from C. hocJistetteri Mayr. (New Zealand), C. lifuanus 

 Montr. (N. Caledonia) and C. bergrothianus Kirk. (Fiji), by its much smaller 

 size. Apparently closely related to C. fungicola Kirk. (Fiji), from which it 

 differs by relative lengths of the antennal segments.

Colour. — 9- Ps-le ferruginous brown, somewhat darker over the head, 

 anterior lobe of pronotum, and scutellum ; eyes reddish, antennae (first and 

 second segments), anterior processes of head and lateral processes of pronotum, 

 fulvous-yellow ; legs pale fulvous-yellow, apices of femora and the tarsi fuscous ; 

 apex of second antennal segment moderately infuscate. 



Structure. — Head about as long as broad (26 : 27), apical processes long, 

 extending slightly beyond middle of first antennal segment ; consisting of two
