1870. 7k 
Abdomen above, brownish-yellow, with a black streak along the sides ; side margins 
black, with a small yellow spot at the lower angle of each segment ; genital 
segment yellow, sides piceous; underneath black, genital segment yellow. 
Length 1 line nearly. 
Undeveloped form, 2 . 
Very similar to the ¢ in all respects, except that the posterior 
margins of the segments of the abdomen, on each side of the dorsal 
line, are black. Length 1 line. 
Larger than L. lepida, and at once to be distinguished from it by 
the absence of the minute white spots on the pronotum, and the less 
prominent black spots on the elytra. 
We know of only two examples: one (2) taken by Mr. T. J. Bold, 
in Gosforth Woods, near Newcastle-on-Tyne, in October ; and one( ¢) 
taken at Abbey Wood, in July (Scott). 
Species 29.—LieuRNIA NIVEIMARGINATA. 
Delphazx thoracicus, Marshall, Ent. Mo. Mag., iii, 269 (1867). 
Undeveloped form, 3. 
Elytra black, posterior margin white. Abdomen black, last seg- 
ment above, and the genital segment, margined with white. 
Head brown ; crown, the two basal fovee distinct but not deep, the anterior one 
faint. Face and clypeus dark brown; keels paler, on the forehead almost obso- 
lete ; cheeks brown. Antenne brownish-yellow. 
Thorax: pronotum white, the anterior margin brown; keels distinct; seutellum 
yellowish-white, middle keel more distinct than the side ones. Elytra black, 
shining, half the length of the abdomen, posterior margin rounded, white, 
nerves prominent. Legs fuscous-brown; tibie and tarsi paler, 3rd joint of the 
latter, black. 
Abdomen black, shining, margin of the last segment above, white, side margins 
very narrowly pale; genital segment above, and the posterior margin on the 
sides, narrowly margined with white. 
Undeveloped form, ° . 
Scutellum yellowish or white. lytra pale brownish, posterior 
margin white. dbdomen brown, darkest on the sides. All the other 
characters as in the ¢. Length, ¢,1; 9, 1} Imes. 
Most nearly allied to L. leptosoma, but it is larger than that species, 
and differs from it in the absence of the pale sutural region of the 
elytra, and by having the scutellum white. 
Taken by the Rey. T. A. Marshall at Wimbledon, in September, 
on marshy places. He referred it to the D. thoracicus, Stal., but as 
that imsect is merely the developed form of the 2 of mesta, Boh., the 
above name has been proposed instead thereof.
