400 Mr. A. E. Eaton on some British Neuroptera. 



Bereodes, nov. gen. 

 The second joint of the labial palpi is equal to the third in 

 length; the first joint is minute. The second joint of the maxil- 

 lary palpi is shorter than the fifth, equal to the fourth, and 

 longer than the third; the first joint is minute. Ocelli absent. 

 The first two joints of the antennae are very much stouter and 

 longer than the others. Spurs 2.2.4. There is no sexual 

 difference in the neuration of the wings, excepting that the 

 short nervure at the base of the fore wings behind the cubitus is 

 greatly thickened in the male, and that the costule (?) in the 

 hind wing is furcate in the ? (fig. 9), and simple in the ^ 

 (fig. 10). The fore wings are very hairy, and have long 

 fringes. The neuration is indistinct. The transverse veins are 

 alike in both sexes. Fig. 10 represents the neuration of the J^,

according to Mr. M'Lachlan. Any discrepancies that can be 

 detected between the two figures, other than those 1 have al- 

 ready mentioned as dependent on the sex, are due to a difi\jr- 

 ence of opinion respecting the neuration. The lower edge of 

 the last abdominal segment in the $ is produced upwards and 

 turned in. The appendices of the ^ are well developed, but are 

 not easily seen, on account of the last segment being clothed 

 with long hair on the sides. In both sexes there is a tubercle 

 on the last ventral plate, clothed with erect hairs. 



B. minutus, Kolenati. 



Length 2-2^ lines. Antennae and maxillary palpi sooty; the 

 first two joints of the one and the first four joints of the other 

 are clothed with spreading hairs. Labial palpi testaceous. 

 Wings fuscous, the anterior with suberect black hairs on the 

 veins near the inner margin. Legs testaceous, with fuscous 

 joinings. Hairs on the tubercle of the last ventral plate fulvo- 

 griseous. The app. inf. of the $ are obtusely triangular; in 

 the c? the app. inf. are short, very like spear-points, and are testa- 

 ceous. The app. sup. are difficult to describe : they are filiform, 

 except at the base, which is greatly expanded in the form of a
