apically, so that the first posterior cell is not at all narrowed in the 

 apex of the wing; and the lower posterior angle of the metapleura, 

 and the hind coxae at apices above, are without hairs. 



The genotype is Herina chalyhea Doleschall. Before me there are 

 four other species besides the genotype, data upon which are pre- 

 sented below. 



PSEUDEPICAUSTA CHALYBEA (Doleschall) 



Herina chalytea Doleschall, Natur. Tijd. v. Ned.-Iud., vol. 17, p. 125 (1858). 



A metallic blue species, with a large fuscous mark on the apex of 

 the wing the inner margin of which extends from the costa about 

 midway between apices of first and second veins obliquely to margin 

 beyond the tip of fourth vein, a dark costal streak, most intense in 

 the subcostal cell, and dark clouds on the outer and inner cross veins 

 least conspicuous on the latter. 



The vertex has but two strong bristles, the scutellum has six 

 bristles, the two near base and two on disk shorter than the apical 

 pair; and the mesopleural strong. 



Locality, Manila, P. I., December, 1924 (R. C. McGregor). 



PSEUDEPICAUSTA ANGULATA Hendel 



Pseudepicausta angulata Hendel, Abhand. k. k. Zool.-Bot. Gesellsch., Wien, 

 vol. 8, p. 118, 1914. 



This species is very similar to the genotype, but the wing markings 

 differ in that the apical fuscous mark is carried less distinctly behind 

 the third vein at apex, the costal streak is not appreciably paler be- 

 tween apex of first vein and inner edge of the apical mark, and there 

 is a fuscous cloud along the fourth vein connecting the two clouds on 

 the inner and outer cross veins. 



Structurally the species differ in the armature of the vertex, rnigvr- 

 lata having four bristles, the additional pair being central and cruci- 

 ate. Both species have an occipital bristle, and the third antennal 

 segment extending to below level of epistome. 



Locality, Penang (C. F. Baker). 



PSEUDEPICAUSTA BATAVIENSIS (Schiner) 



Stenoptei'ina batavicnsis Schinek, Reise d. Novara, Diptera, p. 288 (1868). 



I have seen one female of this species. It has much the appear- 

 ance of angndata, but the cross veins are but slightly clouded, the 

 clouds are not connected along the fourth vein, the frons is much 

 more narrowed at vertex, and the second and third abdominal ter- 

 gites are white dusted at apices. The four vertical bristles are well 

 developed, and there are no distinct orbitals; scutellum with six 

 bristles, one pair on disc a little smaller than the others. 



Locality, Wai Lima Z., Sumatra, 1921 (Karny and Siebers).
