 The translator takes this opportunity of repeating that, 

 although it has been found impracticable to republish the 

 figures accompanying the original papers, the references 

 to those figures have been retained in the translation ; the 

 figures themselves are easily accessible, as the papers appear 

 in the published Transactions of the Netherlands Entomo- 

 logical Society. J. W. M.

We have here a species very nearly allied to the preceding 

 (Dineura Alni), but of an entirely different habit, Dineura 

 Alni being solitary in the larva stage, and the larvae of the 

 present species being always found living together in great 

 numbers. In the month of August, 1864, 1 found it at 

 Schothorst, near Amersfbort, in a copse of young birch, in 

 such numbers that I counted more than thirty young larvae 

 on one leaf, and 1 could easily have collected a thousand 

 caterpillars. I vpill begin by a description of the female 

 (fig. I). It is 9 or 10 mm. long, expanding to 18 mm., 

 short, of a compressed form, and, with the following excep- 

 tions, entirely of a shining orange colour. The eyes are 

 grayish black; ocelli topaz colour; antennae and labrum 

 brownish black ; mandibles brown, the under surface of the 

 thorax having shining brownish black spots, the dorsum of 

 the metathorax being also of this lint, and having the 

 cenchri ivory-white ; the ovipositor is black ; the under side 

 of the femora, the tips of the posterior tibiae, and the whole 

 of the posterior tarsi, are brown ; and, lastly, the posterior 

 tibiae, with the exception of the above-mentioned brown tips, 

 are of a pale faded red ; the wings are smoky, which tint 

 becomes paler towards the exterior margin ; the stigma, the 

 costa and the post-costal nervure are orange; the other 

 nervures are brown, the exteino-medial nervure and its 

 branches being dark brown; the nervure between the first
