NOTES ON CLINOCOBIDAE, A FAMILY OF RHYNCHOTA, 

 WITH THE DESCRIPTIONS OF A NEW GENUS AND 

 SPECIES.

(Tc.\t-f5gs. 1—4.) 



ON page 03 of the present volnuje we stated that tmir principal types of bristles 

 are found iu the Clinocoridae, and gave illustrations of these types. The 

 most remarkable type is the one in which the conve.x side of the curved bristle 

 appears denticulate in a lateral a-sju'ct. This kind of bristle is only fonnd in the 

 genera CUnocoris and OeciacHS, wherea.s the largest and most modified bristles of 

 the other genera are only dentate at the ape.f. This difference in the bristles 

 conpled with distinctions in the jjroboscis and sterna splits the family np into the 

 following groups : 



A. Subfamily Clinocorinae nov. 



Proboscis at most reaching in between the fore-coxae. The large bristles 

 broad, curved and denticulate on the conve.x side. Mesosternnm broadly rounded 

 posteriorly. Metasternum broader than the mid-femur, being as long as it is 

 broad, and posteriorly rounded-truncate. Raised mesial portion of basal abdominal 

 sternite hardly at all narrowed forward. Eighth abdominal segment of S strongly 

 asymmetrical. ^Here belong the genera Clinororis and Oeciacus. 



B. Subfamily Cacodminae (Kirk, indcscr.). 



Proboscis at most reaching in between the fore-coxae. The large bristles 

 dentate only at the tip, not on the convex side. Mesosternnm snbtriangular. 

 Metasternum more or less lozenge-shaped or ovate, tapering forward, much longer 

 than it is broad, about as wide as the mid-femur. Raised mesial portion of basal 

 abdominal sternite narrowing anteriorly. Eighth abdominal segment of S almost 

 symmetrical. — Here belong Cacodmus, Lnxanpia, and the new genus descriljed 

 belo\v. 



C. Subfamily Haematosiphoninae nov. 



Proboscis extending beyond the mid-coxae. The large bristles curved, rather 

 broad, dentate at the tip, but not on the convex side. Mesosternnm rounded. 

 Metasternum narrow. Raised mesial portion of basal abdominal sternite also 

 narrow, anteriorly narrowing. — Here belongs llcinnatosiphon. 



The Clinocorinae are further characterised by the scutelhim, which bears a 

 number of bristles resembling those of the pronotum and elytra, while the 

 .scutellum of the Cacodminae has only small hairs.
