H. Gyllenhalii^ an insect which has not yet occurred south of the 

 Tweed, — and the latter by the B. Skrimshirii^ described in our 

 last number by Mr. Westwood, under the name of B, Stephensii. 

 The Hymenopterous genera are seven in number, and also pre- 

 sent no striking novelty to the general student, although several 

 of them were previously unknown to the English Entomologist. 

 The single genus of Neuropteru figured, is extremely interesting. 

 It is the Boreus, Lat,, and is founded on the Panorpa hyemalis^ 

 Linn., an extraordinary insect, which was first added to our Fauna 

 by Dr. Leach. 



The new genera proposed are entirely confined to the Lepi^ 

 doptera, twelve of which are illustrated in the volume before us. 

 Of these four are now for the first time distinguished. The first 

 of them, Chauissa, is closely allied to Cleora, from which it is 

 distinguished by the short pectinations of the antennae of the 

 males, which give to them a robust and compressed appearance. 

 It includes the Geometrce serotinaria, pullaria^ and obscuraria^ 

 together with the C. operaria^ which is figured as the type, and is 

 new to Britain. 



Alcis, the second new genus, may be distinguished from Um- 

 palus, by the males being invariably smaller than the females, the 

 eyes being larger and more distant in front, the palpi more 

 porrected, shorter, and not hairy, the maxillae very long, and the 

 antennae not pectinated to the apex. Its type is the Geometra 

 repandaria^ Linn. Eleven British species are enumerated as con- 

 tained in it, three of which, including the J, sericeariUy which is 

 figured, were previously und escribed. 



Analogous to Alcis^ in that section of the Phalcenidce^ in which 

 the antennae of the males are simple, is the third new genus, 

 Macaria. Of this the Phalcena liturata is figured as the type^ 

 It includes six other British species, among which are the P* 

 prcenotata^ P. notata^ &c. 



The remaining new genus is divided from the Tortrices under 

 the name of Cnephasia. The wings of these insects are folded 

 very differently from those of the other species of the family, 

 bearing in this respect a stronger affinity to the Cramhi, Its type 

 is the Phalcena Logianuy Linn., and it includes eight other British
