126 SERRICORNIA. [Eubria. 



thence to about a third of the length of the elytra where it stops, the 

 second is widely interrupted at base and apex, the third and fourth nearly 

 unite at base and quite unite at some distance from apex, and the fifth 

 almost encloses the fourth but ceases before base and apex; legs long and 

 slender, obscurely testaceous with femora usually darker, tarsi elongate 

 and slender. L. 1^-2 mm. 



In moist, damp places by small streams and watercourses ; very rare ; first dis- 

 covered in BriUiu by the Rev. H. Matthews near Weston on the Green, Oxfordshire, 

 who, in company with his brother the Rev. A. Matthews, took a number of specimens 

 on small sticks submerged in a narrow rhein or watercourse ; Glanvilles Wootton (Dale 

 and Wollaston) ; Scarborough (II. Lawson); Northumberland district "upon Samolut 

 valerandi in a ravine a little to the north of Castle Eden Dene " (Rev. W. Little). 



LYCIDJE. 



The genera belonging to this family are by many authors regarded as 

 merely a tribe of the Lampyridse, from which they differ by having the 

 trochanters not applied to the femora, but in a line with them, and by 

 the fact that the intermediate coxa? are not contiguous but rather widely 

 separated ; the antennae are always more or less serrate, often pectinate ; 

 the claws are simple and the abdominal segments are simple in both 

 sexes ; many of the species have the elytra much dilated, the insects in 

 some cases being almost circular ; the colours are often very bright, 

 orange or scarlet, and the sculpture is very peculiar, the elytra being 

 often strongly ribbed, with transverse raised lines forming an areolate 

 network ; the eyes are larger in the male than in the female, but never 

 very large ; the antennae are 11-jointed, with the second joint often very 

 short, and the tarsi are 5-jointed ; the species are diurnal, and are found 

 on the leaves of plants and on flowers ; they are carnivorous in their 

 habits. 



The larva of Dictyoptera sanguinea (which was formerly reputed as British) is 

 described by Erichson (Wiegm. Arch. vii. p. 93); it is flat and linear, narrowed in 

 front and behind, deep black above, and whitish with black spots beneath ; the last 

 segment is corneous, reddish in colour, and terminates in two projecting bent horny 

 processes ; it occurs under bark of oak. 



The greater number of the species which belong to the Lycidae are found 

 in the tropics ; they are poorly represented in Europe by seven genera and 

 about twenty species, of which three only occur in Britain ; in general 

 appearance and colour these strongly resemble one another, but are now 

 referred to three separate genera ; the synthetic genus Homalisus ought 

 perhaps to be removed from the family and regarded, as is done by some 

 authors, as a separate family in itself. 



I. Antenna; contiguous at base with forehead not or only 



slightly prolonged between them ; sculuture of interstices 

 of elytra very distinct. 



i. Third joint of antennae plainly longer than second, not 

 transverse ; elytra with a double series of areolets in 

 each interstice EBOS, Newm.
