shining, black pilose ; venter yellow. I^egs with the 4 posterior femora blackish at 

 the tip. 



Wings with the same pattern as in the preceding, but the veins are fuscous and 

 the broad band on the fore border is blackish ; the costal cell is light ; the 3 hyaline 

 spots at the costa are in the same position. The 2 bands of the hind border are 

 brownish ; that on the hind cross-vein is often evanescent and there is no trace of the 

 longitudinal band in the middle of the third posterior cell. 



Two specimens caught by Dr. Annandale at the same place as the preceding : 

 Paresnath, W. Bengal, 4300 ft., 9th and nth April 1909 (^ff-^, -ff-)- 



If it is proved that this species is the female of Chaetellipsis paradoxa, we have 

 here the most remarkable case of sexual dimorphism as yet known in the family.

As restricted here, this genus is easily known by the pubescent arista on the upper 

 side only, the oblique position of the hind cross- vein, and the very peculiar pattern 

 of the wings. 



Head as broad as high ; face very broad beneath, flat, the epistome not pro- 

 minent ; cheeks rather broad ; antennae inserted on the middle of the eyes, short, 

 the third joint double the length of the second, rounded at the tip ; arista long, shortly 

 pubescent on the upper side only; oc. long and robust ; or. 2. 2 ; vt. 2; pvt. parallel, 

 yellow ; occipital row with black bristles ; genal bristle indistinct ; palpi shortly 

 bristled. 



Thoracic chaetotaxy complete ; dc. nearer to the suture than to the scutellum ; 

 I mpl. ; pt. strong; mesopleura with long and stout hairs. Scutellum swollen, 

 with 4 bristles and stout hairs on the middle. Abdomen broad and short, bristly 

 on the sides and at the end ; male genitalia prominent ; ovipositor flat, short. Legs 

 short and robust ; front femora of the male much more bristly than those of the female ; 

 middle tibiae with a single spur ; bristles of the row of the hind tibiae rather long. 



Wings very broad and short, with yellow and brown cross bands and black streaks 

 on the base ; costal bristle short, but distinct ; ist vein short ; 2nd straight ; 3rd 

 straight, bristly throughout its length; last portion of the 4th vein curved ; small 

 cross- vein on the middle of the discal cell ; hind cross-vein oblique , the inferior angle 

 of the discal cell therefore acute ; second basal cell a little dilated ; anal cell drawn 

 out into a point as long as the 2nd basal cell ; anal cross- vein very deeply curved in 

 the middle. 



Type : Trypcta capitata, Wiedemann, 1824. 



As here restricted, the genus will comprise only a few species ; the spatulated 

 appendages of the front of the male are not present in all the species. The African 

 species with feathered legs in the male seems to belong to a peculiar genus. 



I think that the name Ceratitis is not preoccupied in zoology by Ceratites, and I
