vescent. Legs white. Tarsi white, spotted with fuscous. Anterior wings white (with 

 more or less of a yellowish tinge occasionally) : on the costa are three fuscous streaks, 

 and on the inner margin two ; the first costal streak begins a little beyond the middle 

 of the wing, and points towards the anal angle ; it meets the first inner marginal 

 streak, which begins a little before the middle of the wing, forming with it an acute 

 angle; the second pair of streaks is margined inwardly with pale fulvous ; these meet 

 at an obtuse angle, and the costal streak is at right angles with the costa ; just beyond 

 these two streaks is a white triangle on each margin, the remainder of the wing being 

 pale fulvous ; the third costal streak resembles the second, and is also followed by a 

 small white triangle ; at the apex of the wing is a round black spot, round which, in 

 the cilia, is a series of black dots from the outer margin of the last costal triangle to 

 the anal angle : cilia pale, with two dark patches in continuation of the two costal 

 streaks, and a dark mark arising from the last, and continued to the extreme apex. 

 Posterior wings clear gray ; cilia whitish. 



A most abundant species, frequenting oaks. 



Zeller says of it, " This species is one of the most abundant near Glogau ; it flies 

 in May, July and August, principally in oak woods and hazel thickets. It is found 

 in June in the Zoological Gardens at Berlin. Mann collected it at Reichstadt, in 

 June, off larches ; near Vienna, in June and August, off beeches, on which he also 

 found the caterpillar." 



This insect having been universally admitted as the Cramerella of Fabricius, I 

 have not ventured to oppose an unanimity so unusual ; but I will just remark here 

 that Fabricius says *' with three opposite oblique fascise." Now this has three costal, 

 but only two inner marginal fasciae. Zeller imagines Fabricius took the dark mark 

 in the fringe for a third fascia ; perhaps so : at any rate it may as well bear the name 

 of Cramerella till a new species turns up which will agree better with the Fabrician 

 description.

Occurrence of Vernal Diptera in Berwickshire, with Descriptions of two British Species. 

 By James Hardy, Esq. 



Although we have hitherto had " March weather " in its fullest rigour and incon- 

 stancy, several Dipterous insects have already appeared to enjoy the intervals of sun- 

 shine between the reign of storm and cloud that distinguishes this period of the " un- 

 confirmed year.'' Many of them have, doubtless, weathered the winter ; but now their 

 numbers are augmented ; their sports are rendered more accordant with the character 

 of the season ; and the pleasure of observing them is increased, by their being associated 

 with vernal aspirations, as the harbingers of the gay procession to succeed, and the hours 

 of happiness in the study of the bright throngs kept in store for all who will 



" Come forth into the light of things," 

 and accompany Nature, through her series of evolutions of myriads of existences. 



As yet there have appeared only such kinds as depend for their sustenance hut little 

 upon the flowery tribes, of which the coltsfoot and the opposite-leaved golden saxi-
