208 THE ENTOMOLOGIST. 



first joint of the posterior tarsi with short ferruginous pu- 

 bescence; the wings fulvo-hyaline, with their apical margins 

 broadly bordered with fuscous ; the nervures fusco-ferrugi- 

 nons. 



This species most closely resembles the B. opulentus from 

 N. China, which I described in ' The Journal of Entomo- 

 logy,' vol, i. p. 153; but it is a larger species, and the ful- 

 vous pubescence covers an additional segment of the abdo- 

 men : the wings of B. opulentus are entirely brown. 



Crabro vagaius. — Female. Length 4 lines. Black, the 

 abdomen with yellow maculae. Head subquadrate, wider 

 than the thorax, longitudinally rugose-striate, the striation 

 curving on the vertex laterally and running down the cheeks ; 

 the clypeus covered with bright silvery pile ; the scape with 

 a yellow line outside; the ocelli in an angle on the vertex. 

 Thorax closely and coarsely punctured ; the metathorax 

 transversely striated and with a central channel, the semi- 

 circular space at its base not distinctly defined, but obliquely 

 striated ; the wings hyaline and iridescent, the nervures tes- 

 taceous, the tegulse black ; the tibige outside, and the ante- 

 rior femora beneath towards their apex, yellow ; the spines 

 at the apex of the tibiae yellow. Abdomen subpeliolate ; the 

 second segment with an oblong-ovate macula on each side, 

 the fourth and fifth with a widely-interrupted narrow fascia 

 at their basal margins. 



This is the only species I have seen of the genus Crabro 

 from Japan : it very closely resembles the European species 

 C. vagus, but the sculpture of the head is very different, as 

 well as thai of the metathorax.

A Life'history o/Druida parviceps, Newman. — The larva 

 of this species is a birch-miner; there are also two other 

 kinds of Tenthrediiiideous larvae, whose economy 1 am 

 acquainted with, that blotch the leaves of birch. It is soli- 

 tary in its habits, the perfect insect laying only a single eg^ 

 on the leaf, always, I believe, depositing it on one side or at 

 tip of the leaf, never in the central parts. The newly-hatched
