AGRIADES THETIS. 851 



during the second week of June, 1907. Kowland-Brown records two 

 exceptionally small examples in the Val Muerta, near Beaulien, and a 

 small $ at Digne, in October, 1902. Bond exhibited (Proc. Ent. Soc. 

 Lond., 1868, p. xlii) at the meeting of the Entomological Society of 

 London, a $■ of extremely small size. Others have already been 

 mentioned, antea, p. 336.

This name was given to include the many known aberrations of 

 this species in which the spots on the underside of the wings are 

 elongated or united into the form of streaks. Many different minor 

 striate forms in our collection were brought together under this name, 

 for which it was thought inadvisable to find different names. Since 

 then, however, many of these very common aberrations have been 

 separately named by CoUrvoisier and others, and, as they fall into 

 two groups, viz., (1) those which have become striate owing to the 

 extension of the normal spots, (2) those which have become striate 

 owing to the union of two or more spots, it may be well, henceforth, to 

 restrict the name striata to the first group, and call the second conjuncta. 

 One of the earliest recorded examples of this restricted striata form, is 

 that noted as having been exhibited by Bond, December 7th, 1868, 

 and described (Proc. Ent. Soc. Lond., 1868, p. xlii) as a ^ with a 

 number of broad bars of black on the underside of the forewings. 

 Nussey records (Proc. Sth. Lond. Ent. Soc, 1893, p. 44) an aberration 

 in which the spots beneath are developed into broad streaks. Joy also 

 exhibited a $ , described (Proc. Ent. Soc. Lond., 1902, p. xl) as being- 

 striped on the underside. The finest specimen of the ab. striata (sens, 

 restr.) known to us, is that figured (Ent., xxxiii., p. 281) by South, 

 and described as a $ , captured at Folkestone in July, 1899, in which 

 every spot on the underside of both fore- and hindwings, is lengthened 

 in the direction of the base, including not only the spots of the sub- 

 median rows, but also the basal spots ; the ground colour of this 

 particular example is whitish, clouded w r ith grey, the ordinary ante- 

 marginal orange lunules being in their usual position, but falling, in 

 this example, at the outer extremities of the black bars on the hind- 

 wings.

This form was included in our ab. striata (sens, lat.), and will fall 

 before the latter name, if one name be used to include all the striate 

 forms. It is a most interesting form, and the development of the
