in 1893. A slender insect, not unlike an Asclera (fara. 

 (Edenieridse), green or bluish green, with the palpi, an- 

 tennne, and sometimes the tibiae and apex of the abdomen 

 also, testaceous or flavous ; the autennse very slender ; the 

 head small. Two males have been dissected. I. flavicoUis 

 appears to have been unknown to Pic. 



14. Idgia flavirostris. 

 Idyia Jlanirostris, Pasc. .lourn. Ent. i. p. 43 (April 1860) ; Fairin. A.nn. 

 Soc. Eat. Fr. (6) ix. p. 44 (1889). 



S ' Eyes small, distant, as in ? ; anterior tarsal joints 1-3 

 with a comb along their inner edge. Genital armature 

 (PI. XI. fig. 14) : lateral lobes long, narrowed outwards, their 

 apices truncate and hooked beneath; median lobe gradually 

 narrowed, curved upward at the tip. 



Hah. China {Mus. Brit.), Chusan Is. (/. J. Walker), 

 Ta-maon Isl., Hong Kong {Mus. Brit.). 



Of the eighteen examples of this species before me, in- 

 cluding the type, one only, from the Chusan Is., is of the 

 male sex. A close ally of /. flavicoUis, with a longer pio- 

 thorax and very elongate elytra, the anterior portion of 

 the head, palpi, basal joints of the antennae, prothorax, and 

 femora testaceous. The head is small and comparatively 

 short. The tarsal claws are distinctly widened to about tiie 

 middle. An allied form from China has been described by 

 Fairmaire under the name /. muupinensis. 



15. Idyia virescens, sp. n. 



$ . Very elongate, nai'row, subopaque. finely cinereo- 

 pubescent, and sparsely nigro-setose ; obscure metallic green, 

 the anterior half of the head, palpi, antennse, underside of 

 prothorax, abdomen, coxae, femora, and tibiae in part, testa- 

 ceous. Head scabroso-punctate, small, slightly produced in 

 front, excavate between the eyes, the labrum transverse ; 

 eyes distant; apical joint of maxillary palpi elongate; 

 antennae very slender, long, joints 3 and 4 equal in length, 

 those following still more elongate. Prothorax longer than 

 broad, wider than the head, somewhat dilated at the middle, 

 opaque, densely, very finely scabroso-punctate. Elytra very 

 elongate, much broader than the prothorax, rounded at the 

 tip ; densely, rugulosely punctate, each with five series of 

 conspicuous granules on the disc, the margins crenulate. 

 Legs very long and slender ; tarsal claws widened to about 

 the middle. 



Length (excl. head) 8;^^, breadth 2 mm.
