 Habitat ? In Mus. Soc. Linn. Lond. 



I greatly regret that I can give no account of the habitat of this curious 

 species, which is contained in the cabinet of this Society. The very peculiar 

 colouring of the wings is owing to the more complete development of that cha- 

 racter which is found throughout the group, namely, the tendency to an in- 

 crease of colour at the base of the posterior branches of the postcoital vein, and 

 in the small transverse veins connecting the longitudinal ones: hence in this 

 insect we find the middle vitta extending over that part of the postcoital vein 

 which emits the posterior branches, whilst the posterior vitta extends over the 

 series of small transverse veins ; the short transverse apical fascia in like □ 

 ner covers the two very short transverse veins connecting the mediastinal with 

 the postcostal, and the latter with its last branch. On comparing the figure 

 of the fore-wing with that of Derbe semistriata, it will be found that the chief 

 difference consists in the branches succeeding the small transverse vein (con- 

 necting the postcostal and median veins) running up to the postcostal vein: 

 instead of being united, as in Derbe, to a branch which has the appearance of 

 being a continuation of the median vein. In Mysidiu, indeed, we find this 

 branch wanting, and, consequently (except in the number of the branch* 

 the fore-wings of Mysidia and Zeugma agree together.
