Habitat: Taiti. 



For reasons stated under Ccdiisa, I have separated this species 

 from such forms as Lamcnia vnlt^aris. I consider it likely that 

 Tliyroccphaliis Kirk, will eventually be sunk into this genus. 



Thyroccphalus Kirk. 



H. S. P. A. Ent. Bull. I. 429. Bull. Ill 169, text fig. 2. 



The type of this genus (Iciicoptcnis), owing to a defective 

 specimen, was characterized as having a 5-carinate scutellum and 

 so illustrated ; it has only a central carina. The tegmen figured 

 in Bull. Ill has the first cubitus vein abnormally approaching the 

 media (media-cross vein very small), another specimen has it 

 absolutely touching. This genus is near to Stal's Lamcnia and 

 may be eventually synonymized therewith. 



(1) T. fiaz-o-monilc sp. nov. ((5 2). 



Pronotum, head, legs and ventral side of thorax and abdomen 

 yellow, scutellum dark brown, distal portion of facial keels, cly- 

 peus, mark on metapleura, anterior and middle tibiae and upper 

 portion of obdomen fuscous ; tegmina hyaline, slightly opaque, 

 brown veined, the brown spreading out broad toward base of 

 veins, filling most of the clavus ; wings hyaline, brown-veined. 

 Tegmina, wings and body covered with white flocculent waxy 

 secretion. Genital style with fairly long, pointed and curved 

 apex ; anal segment narrowly rounded at apex. 



Length of body 4.6 mm. ; tegmen 4.7 mm. 



Habitat : Amboina, Ceram, and Larat. 



The nymph of this species has a broad face, the sides outwardly 

 curved, narrowest at apex and base, a wide area, about a fourth, 

 along each side being beset with wax pits.
