2. Nigra, utrinque macula magna a basi usque medium, suturam haud attingente posticeque oblique

Among the ten examples examined there is no trace of intermediate gradation between 
the two distinct modes of elytral coloration above described. The form with black 
apical half of the elytra resembles very much T. lycinella, but that species has the base 
of the fourth antennal joint clothed with bushy pubescence like the whole of the third, 
as in the majority of the Tyrinthic, and the lateral carina of the elytra (more obtuse 
than in 7. diformis, and scarcely to be termed a carina) does not coalesce with the 
lateral margin, but runs parallel to it. 
4, Tyrinthia photurina. (‘ab. XXV. fig. 23.) 
T. biformi affinis, elytris similariter formatis. Elongata, parum convexa, postice gradatim paullulum dilatata, 
nigra, subopaca; capite antice rufo, thorace supra cinereo-ochracea macula magna triangulari medio-basali 
nigra, elytrorum carina incrassata cinereo-ochracea ; antennis nigris, articulis 2°, 5° et 6° totis, 4° apice et 
7° basi, albo-testaceis, 3° toto et 4° basi supra pilosis infra dense barbatis, 4° apice 5°-11™ totis infra ciliatis ; 
capite inter antennas excavato; thorace trapezoideo; elytris apice singulatim subacute rotundatis, epi- 
pleuris ultra medium nullis, carina incrassata obtusa pone medium cum margine coalescente ; coxis quatuor 
anticis et femoribus basi testaceis.

2. Lycidola unicolor.

elytris paullo post humeros dilatato-explanatis undique confertissime punctulatis utrinque costis quatuor

Differs from LZ. belti and other species of the genus in the much shorter third 
antennal joint, which is of similar length, thickness, and density of pubescence to the 
fourth joint ; the dilatation of the elytra is not quite so wide, and its margin describes 
a much more regular curve. 
3. Lycidola isabellina. (Tab. XXV. fig. 24.) 
Quoad formam Lycaneptie amicte (Klug) similis, sed ad gen. Lycidolam pertinet articulis antennarum 3° et 4°
