MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 69 



base, to just above base of 4, upper parting vein from beyond middle 

 distance 10-11, to above middle distance 6-7. 



Hindwing with 2 from 2/3, 3 and 4 connate, 5 moderately approx- 

 imated, 6 and 7 approximated toward base but well separated. 



Male genitalia: Tegumen slender and elongate. Uncus bandlike, 

 curved, crowned with two long, divergent pencils of hairs. Vinculum 

 depressed. Valva deeply cleft into an oval and hairy sacculus and 

 a more or less hooked and ventrolaterally dilated, rather rigid cucul- 

 lus. Aedeagus large, gradually attenuated. Cornutus, a long spine. 



Female genitalia: Sterigma little modified, lamella antevaginalis 

 being a slender crescentic sclerite; lamella postvaginalis a weak and 

 broad transverse band, rounded at the sides and broadly excised in 

 middle of lower edge. CoUiculum absent. Ductus bursae rather 

 long, gradually dilated. Corpus bursae ovoid, with a finely punctu- 

 late wall. Signum single, an oval, colored sclerite with well-defined 

 edges, a central small hollow spine. 



Type species: Grapholitha schistaceana Snellen, 1890. 



A peculiar small genus; the bifid valva and the long- tufted uncus 

 are characteristic, as well as the markings of the forewings. Except- 

 ing the type species, Cydia isogramma Meyrick, 1908 (Ceylon and 

 South Africa) belongs to this genus.

References to this species are scattered through the applied ento- 

 mological literature. It is a notorious pest, a borer of the young 

 shoots of sugar cane plants (Saccharum dulce).
