Var. DELAGOENSIS. 
Smaller and blue-black, the pubescence on the upper side almost 
obliterated ; male and female without red frontal macule ; the metasternal 
red patch broadly triangular in both sexes ; the sexual characters of the 
male, as well as the shape of the genital clasps, are however identical. 
Length 13 mm. ; width 4 mm. 
Hah. Mozambique (Delagoa Bay). 
PSALYDOLYTTA, n. gen. 
This genus differs from Gyaneolytta and Cantharis in the extremely 
slender and elongated antennae, the joints of which are almost cylindrical; 
the very long basal joint slightly thickened at the tip is equal in length to 
the third, the second, also cylindrical, is fully two-thirds of the length 
of the third, and the slightly tapering cylindrical ultimate joint is of the 
same length as the penultimate ; the mentum is more than twice broader 
than long, and very strongly acuminate laterally in the middle, the ligula 
is only moderately ampliate at the anterior part, not very deeply scooped 
there, and the margin is set with a few setae and two very distinct, median 
rigid long bristles ; the labial palps are very long, the penultimate is 
slightly longer than the ultimate which is sub-fusiform but obtuse at 
apex ; the maxillae are short but robust, and the inner lobe is thickly set 
by curved hairs at apex, the upper is very short, but the very dense long 
fulvdus hairs with which the edge is set are describing a broad semicircle ; 
the head is normal, but the enormously developed mandibles are produced 
almost horizontally backwards from the part covered by the incised 
labrum ; elytra cylindrical, singly rounded at apex ; legs and tarsi very 
long, the latter villose underneath, claws very distinctly cleft into two ; 
inner spur of hind tibiae irregularly spatulate lanciform. 
The genus is proposed for Lytta lorigera, Gerst., and also for the 
Senegambian and other species with vaulted mandibles (flavicornis, 
'prieuri, pilipes, &c.). Lacordaire has already indicated (Gener. Coleopt., 
v., 2, 1859, p. 676) that these species, then undescribed, and also Lytta 
fuscicornis, Klug., should form a genus distinct from Gantharis-Lytta.

Monatsb. Berl. Akad., 1851, p. 495 ; Peter's Eeis., 1862, p. 295, pi. 17, 
fig. 10. 
Dark chocolate- brown ; antennae long, slender, joints sub-cylindrical, 
brick-red like the palps, the labrum, and part of the epistome ; mandibles 
very robust, the part uncovered by the labrum when closed is strongly 
deflexed backwards ; head minutely punctate, clothed with a dense flaves-
