DICHROMA EQIJESTRALIS. 225 



are rather short, the tibiae being considerably shorter 

 than either the femur or tarsus ; the middle tibiae 

 are longer and terminated by two spurs, whilst the 

 hind pair, of equal length, have a pair of spurs at 

 the middle and another at the tip. The mediastinal 

 vein of the fore wings is rather short : the post- 

 costal one emits two branches before the junction 

 with the ordinary transverse vein ; the first of these 

 branches is straight and extends to the costa of the 

 fore wings, but the second coalesces with the post- 

 costal vein at a short distance beyond the junction 

 of the postcostal and transverse veins, but almost 

 immediately branches off again in a straight line 

 extending to the costa ; a third branch is also 

 emitted, which is forked before it reaches the costa, 

 the lower branch of the fork extending to the tip 

 of the wing. The median vein extends in three 

 branches to the extremity of the wing, the ordinary 

 transverse vein arising at the base of the last three 

 branches. This transverse vein emits two straight 

 veins, which extend to the extremity of the wings. 

 The bridle consists of several very fine setaa. 



We are so completely ignorant of the character 

 of the smaller exotic Lepidoptera, that we shall only 

 venture to observe, respecting the relations of this 

 group of moths, that they seem to be intermediate 

 between the Lithosiidee and aberrant Tineidae. 



The head, thorax, and fore wings of D. eques- 

 tralis are of a beautiful pea-green, the latter being 

 ornamented with numerous spots and lines of sil- 

 very white, more or less confluent ; three of these
