Cyphus cyanipes F. and C geniilis Oliv. belong to the 

 genus Compsiis ; but C*. chrysis F. I am unable to place, for 

 I know of no insect that resembles Ohvier's distinctive 

 figure of the species; it seems very doubtful whether 

 the insect really came from the East Indies, as indicated 

 by Fabricius, and I should prefer to refer it provisionally 

 to the genus Compsus. C. bispinus Boh. and C. lugubris 

 Boh. are more nearly related to Naupactus, and the genus 

 Canephorus has already been erected for their reception 

 by Kirsch (1889). C. ejfusus Pasc. and C. sigillatus Pasc. 

 (1880) are referable to the genus Pseudocyphus Schaeff. 

 (1905). Finally, C. mucoreus Kirsch (1889), from Peru, 

 appears to belong to the genus described below under the 

 name of Xestogaster, g. n., judging by its elongate form, 

 shiny black underside and tuberculate mesosternum. 



Genus Stenocyphus, nov. 



Head not constricted behind the eyes. Rostrnm with the lateral 

 edge of the dorsal area rounded off and without an ante-ocular 

 depression; the scrobes very narrow, deep and parallel-sided; 

 the mentum bare. Antennae very slender; the scape clavate and 

 exceeding the cjg. Prothorax with the bisinuate basal margin 

 depressed and fitting beneath the base of the elytra. Scutellum 

 small, but distinct. Elytra narrower at the shoulders than in the 

 immediately allied genera, the basal margins strongly lobate and 

 overhanging; stria 10 broadly interrupted in the middle. Legs 

 rather slender ; the corbels of the hind tibiae bare (except for a single 

 row of scales along the apical margin), not ascending the tibiae; 

 joint 2 of the tai'si as long a« or longer than broad. Sternum with 

 the mesepisterna meeting the eh'tra; the metastcrnum with the
