ANASTREPHA ORNATA, new species 



Female. Head yellow, the third antennal joint twice the second, 

 bordered with brown on front edge ; palpi also tinged with brown at 

 tip ; upper two f rontals turned backward ; back of head with a black- 

 ish spot on each side of the occiput. 



Thorax black with the following parts bright yellow: humeri; a 

 narrow median stripe widening suddenly just before the prescutel- 

 lars where it ends ; a lateral stripe above the root of the wing, extend- 

 ing forward to the suture and inward a short distance on this; all 

 the scutellum except a basal border above ; a stripe on upper mesop- 

 leura and a space below the root of the wing including most of the 

 liypopleura and the side of the metanotum; propleura and region 

 about front coxae ; and a stripe on the upper edge of the sternopleura 

 once interrupted. There is also a reddish rather square spot on the 

 middle of the dorsum, divided by the median stripe ; and the sterno- 

 pleurae are red along the median line. 



Abdomen blackish with wide hind borders of the segments yellow ; 

 sixth segment (ovipositor ) much longer than preceding part of 

 abdomen, round, brown, haiiy. Legs entirely yellow. 



Wings hyaline with yellow and dark-brown pattern much like that 

 of serpentina, but very distinct. The base of the costa has a blackish 

 stripe ending at the tip of the first vein. A second blackish stripe 

 begins at the base of the main stem-vein, fills the first basal to be- 

 yond the end of the second basal, then tapers off on the third vein 

 and ends some distance before the anterior cross vein ; the space be- 

 tween this and the costal stripe is largely filled with yellow. A third 

 stripe begins narrowly at the outer hind corner of the second basal, 

 follows the fifth vein (bulging behind it) more than halfway to hind 

 cross vein, then becoming narrower runs straight in a diagonal direc- 

 tion to the costa, including the anterior cross vein (which is itself de- 

 cidedly oblique to correspond ) ; at the costa it widens again and runs 

 to the apex of the wing, its widest part being where it includes the 

 tip of the third vein. A fourth black stripe includes the anal cell, 

 follows the anal vein to the margin, follows the margin to the pos- 

 terior cross vein, then includes the latter and ends narrowly just in 

 front of the fourth vein, without any trace of an arm turning back 

 to the hind border. The basal half of the discal cell is faintly tinged 

 with yellow ; disregarding this we may consider that the hyaline por- 

 tion is continuous fi^om the second basal to the costa. The oblique 

 position of the anterior cross vein is a striking character. - 



Male. — Only the first and second abdominal segments have black 

 basal border, the others are wholly yellow. 



Length of female, without ovijDOsitor, 6 mm ; with ovipositor 9 mm. 



Leno-th of male 6.5 mm.
