THE ENTOMOLOGIST. 28l 



Several times in the Bernese Alps (where it has a range of 

 three thousand feet altitude), and two other species, A. mac- 

 ceronius and A. maculatus, in South France : in this district 

 the flight of Myrmeleon libelluloides is also a very pleasing 

 object. L. inaroccana is the largest European of its tribe. 

 The hairy Laphriae, in South Europe, are an Entomological 

 aspect which is not witnessed in England : their large size, 

 strong forms, powerful flight, and dart-shaped mouths, enable 

 them to exercise a limitating control over many kinds of 

 insects. 



Ravenna. — Coleoptera: Zabrus gibbus, Anoraala Frischii, 

 Triodonta nitidula, Cryptocephalus Hypochceridis. Neu- 

 roptera : Libellula cancellata, L. coerulescens, L. erythra^a, 

 L. striolata. Diptera: Pangonia marginata. 



T. nitidula was abundant in the forest, but T did not see it 

 elsewhere in Italy. The borders of the marshes and broad 

 ditches about Ravenna swarm with snakes, frogs, and dragon- 

 flies : of the latter some other species were in company with 

 those above mentioned; and the bright crimson L. erythrsea 

 presented a pleasing contrast with the numerous white water- 

 lilies.

Description of the Larva of Boartnia rohoraria. — I am 

 indebted to the kindness of my friend Mr. J. P. Barrett, of 

 Peckham, for the opportunity of watching this interesting 

 species in all its stages. The eggs, which I received on the 

 lllh of July in last year, seemed to be deposited in clusters, 

 were oblong-oval in shape, the colour reddish brown. On 

 July 1 4th they hatched, and the young larvae were at once 

 supplied with fresh oak-leaves, on which they fed so long as 

 leaves were obtainable : this food failing in the autumn, 

 tender oak-twigs were substituted ; and to these the larva? 

 (then having attained a length of three-quarters of an inch) 

 attached themselves by silken threads spun over the twigs, 

 the threads being then grasped by the claspers ; in some 

 instances the threads weie also even spun over the hinder 

 segments of the larvae. In this position they spent the winter
