ij4 Memoirs of the Indian Museum. [Voi,. Ill, 



I take here the genus as proposed in 1869 ; but the name was proposed in 1856 with 

 the type arctii, Degeer {=Trypeta) ; in 1870 signala, Meigen {=RhagoleHs) was pro- 

 posed as the type. For further information see my paper of 1910.

A yellow black-spotted species, with four yellow cross bands on the wings, very 

 like M. pardalina, but besides the generic characters, distinguished by the two apical 

 black spots of the scutellum ; seethe figures and descriptions of the above cited authors. 

 The or. are yellowish and the vt. yellow ; occipital row well-developed, yellow. The 

 thoracic bristles are yellowish at the end, the scutellar ones almost entirely yellow. 

 The two scutellar black spots are separated by a narrow yellow line. 



The species is only known from South Italy and Dalmatia ; the larva lives in the 

 fruits of Zizyphus, as observed long ago by A. Costa, but the metamorphosis has not 

 yet been properly described. 



In the collection there is a single specimen from Calcutta (-ff ^) bearing the label : 

 " Carpomyia sp., fly injurious to Plum in Calcutta; reared in Museum, 4-11-92," 

 and another label which says : "by ' plums ' the fruits of Zizyphus jujuha must 

 be meant, N. A., 1908." 



20. Zonosema, Ivoew. 



Loew, Monogr. Trypet., 43, viii (1862). 



Distinguished by the yellow body, which is without any black spot, by the pointed 

 third antennal joint and the bare third longitudinal vein of the wings. 



Head formed as in the preceding genus, but with the epistome a little more pro- 

 minent ; third antennal joint twice as long as the second, oval-shaped, a little pointed 

 at the tip ; arista shortly pubescent. Oc. strong ; or. 2. 3 ; vt. 2 ; pvt. parallel ; 

 bristles of the occipital row well-developed, black. Thoracic chaetotaxy complete ; 

 mpl. I ; scutellum with 4 bristles. Middle tibiae with 2 spurs. 



Wings narrow and elongate, with the veins all straight : no distinct costal bristle ; 

 first vein short ; third vein bare, parallel with the fourth ; small cross- vein placed 

 after the middle of the discal cell ; posterior cross- vein perpendicular ; second basal 

 ceU narrow ; inferior angle of the anal cell drawn out into a broad point, which is longer 

 than the second basal cell. 



Type : Tephritis alternata, Fallen, 1820. 



I have drawn the above characters from the following Indian species, which differs 

 in some points from the European typical ones ; but owing to the general appearance 

 it is better placed here than elsewhere. The single specimen is moreover badly pre- 

 served.
