(2) lineafa Melichar. 



^ Ventral and lateral edges of pygophor straight; anal segment 

 long, anus in basal third where segment slightly widens, then grad- 

 ually narrows to point, the apical third turned ventrally and clett 

 from apex to angle of head; styles long, narrow, apical third turned 

 upward, apex pointed, basal two-thirds subparallel sided, dorsal mar- 

 gin slightly incrassate, a small quadrate process on inner surface near 

 base. 



Hab. Mount Maquiling, Luzon (Muir, February).

Dr. Melichar in describing L. flavescens (Philip. Jour. Sci. 

 1914, IX, D. 2, p. 179) has placed this genus in the AchiUnae. 

 To this I cannot agree, as this genus has the characteristics of 

 the family (or subfamily) ; should it be upheld then some 

 fifteen or sixteen genera of the Cenchrea group will also have to 

 be moved to AchiUnae. The two following species have the 

 characteristic subantennal plate as long as, or a little longer 

 than, the antenna. 



(1) javanica sp. n. 



$ Stramineous, fuscous over keels of face, clypeus, labium, tibiae, 

 margin of tegulae, tergites of abdomen and genitalia, a dark round 

 spot on propleura; tegmina stramineous, opaque with waxy secretion, 

 fuscous over clavus, along hind and costal margins and an acutely 

 angular mark on margin between subcosta and media; wings opaquely 

 white with waxy secretion, veins brown. 



Ventral edge of pygophor straight, lateral edges rotundate; anal 

 segment large, much longer than broad, basal portion subparallel sided, 

 then gradually narrowed to pointed apex which is turned ventrally, 

 anus about a third from base; styles reaching to end of anal segment, 

 narrow, semispatulate, t^e dorsal edge nearly entire, curving slightly 

 upward and broadly dilatate, the ventral edge roundly produced be- 

 yond the middle and narrowly dilatate, apex pointed and turned in- 

 ward, a small round knob on niner side near base from which rises a 

 small sharp spine.
