terruptions in addition to several smaller ones. Abdomen with 

 dark incisures above, venter brownish. 



Head very finely shagreened throughout, wider than prono- 

 tum, the length of vertex into width between eyes four and 

 two-thirds times; vertex as long at middle as at eyes. Face 

 broader than long; ocelli nearer to median line than to eyes; 

 front about as broad as long; clypeus longer than broad, only 

 slightly broadened apically, the apical margin incurved; lorse a 

 third longer than clypeus and about half as wide. Width of 

 pronotum two and a half times the length, the length about 

 three times that of vertex, the hind margin slightly incurved; 

 surface finely shagreened, medially and on posterior half with 

 rather conspicuous but remote dark punctures. Scutellum about 

 a fourth longer than head and pronotum together, the transverse 

 impressed line strongly angulately bent, the surface posterior 

 to this without transverse wrinkles. Tegmina smooth, shining, 

 and rather thin, with a few punctures along the claval veins; 

 veins strong throughout, the costa conspicuously thickened. 

 Anal segment of female with hind margin truncate or slightly 

 incurved; pygofers long, very slender, and strongly haired, far 

 longer than the lateral plates.

Genus CHUNRA Distant 



The genus Chunra, as described by Distant,^ is a taxonomic 

 puzzle. The diagnosis is not at all diagnostic, most of the 

 characters mentioned being tribal characters. The pronotum 

 is stated to be "twice as long as vertex," which would be a 

 marked character if true, but the figure shows it three times. 



There occur abundantly in the Philippines, as in other Mala- 

 yan and Indian countries, species of idiocerine insects, swarms 

 of which attack the flowers of mangoes, as is recorded by 

 Distant for the species niveosparsus of Lethierry. Distant's 

 figure of niveosparsus shows a strong and continuous supra- 

 frontal carina, which seems to be certainly an error, as does 

 also the form of the clypeus. In the species, as it occurs here, 

 the frontoclypeal suture is quite obsolete. Distant's figure shows 

 the ocelli nearer to eyes than to each other, while he describes 

 the genus Chunra as having them about as near. In the forms 

 of niveosparsus occurring in the Philippines this varies con- 

 siderably, as I shall show. Indeed, niveosparsus, as figured by 

 Distant, fits his description of the genus Chunra about as
