angles about middle, indistinctly tricarinate, especially the lateral 

 ones. Tegmen with long subcostal cell, four median sectors, the 

 first furcate. 



Coicharea dorsalis, West., has a very short subcostal cell and 

 the media arises from the radia about one-third from the base 

 of the tegmina ; the figure of this species also shows an antennal 

 chamber formed by the pronotum (shovdder keels being large 

 and the subantennal process absent) ; therefore maorica cannot 

 be included with dorsalis. Laincnia hk'ci Kirk, agrees with mao- 

 rica, but the facial keels are not so deep. The presence of the 

 median facial keel also divides this genus from Ccnchrca. or La- 

 menia.

 This genus was placed by Alelichar among the Cixiidae, but 

 was considered by Kirkaldy to be a Derbid. My two species, 

 which conform to ]\Ielichar's generic characters and have a sim- 

 ilar tegminal neuration, possess a short apical labial joint. The 

 absence of a distinct subantennal process separates this genus 

 from Thyrocephahis.

PI. I fig. 7. 



Pale yellow ; lateral third of scutellum fuscous, darkest on 

 hind margins ; dorsum of abdomen fuscous ; a round black spot 

 on mesopleura, another on metapleura ; tegmina hyaline, tinged 

 with light fuscous-yellow on distal half ; dark fuscous over costa, 

 along hind margin a narrow mark from radial cross-vein to apex, 

 apical edge and veins fuscous ; wings hyaline, light-veined. Gen- 

 ital style narrow for basal third, then roundly widened to near 

 the truncate apex ; one-third from base there is a short thick bi- 

 lobed process, with small hooks on the lobes and near base, also 

 a small curved spine a little w-ay beyond this process. 



Length of body 3.3 mm. ; tegmen 4.4 mm. 



Habitat : Java. 



* In Mr. Distant's description of this genus I think "face" in the first line 

 should read "vertex" and "vertex" in the fourth line "face."
