126 Mr. G. C. Champion’s Notes on 
grooves beneath; last joint of the maxillary palpi (fig. 4b) elongate- 
ovate, stout, acuminate; antennae (fig. 4a) apparently 11-jointed, 
1 very stout, 2 small, obovate, 3-8 very slender, 3 elongate, 4-8 
short, 9-11 dilated into an elongate compact club; eyes depressed, 
moderately large; anterior tibiae long, narrow, almost straight on 
their outer edge, feebly arcuately dilated towards the base within ; 
intermediate and posterior tibiae moderately long, angularly dilated 
externally; tarsi 3-jointed, long, slender, 1 and 2 each produced 
beneath the succeeding joint, 1 elongate, 2 short, excised for the 
reception of 3, the lobe beneath reaching the middle of the next 
joint, the latter slender at the base, the claws appendiculate ; 
femora stout, clavate, compressed, grooved, received in deep cavities 
of the under surface, those for the intermediate and posterior pairs 
extending outwards across the elytral epipleura and limited behind 
by the curved, cariniform coxal lines; intermediate and posterior 
trochanters large, elongate, laminiform; body hemispherical, 
glabrous above. 
Type, L. diversipes. 
This genus may be known by the strongly retractile 
limbs; the prominent, raised, prosternal chin-piece; the 
long, narrow, sinuous, anterior, and the angularly dilated 
intermediate and posterior, tibiae; the greatly developed 
intermediate and posterior trochanters; the long, slender 
tarsi, with elongate basal joint; and the hemispherical 
almost glabrous body. The head in repose is so closely 
applied to the prosternum that the mouth-parts and 
antennae cannot be seen till the head is forcibly raised, the 
legs also being equally retractile, though the tibial grooves 
are wanting on the anterior pair. The type is a minute, 
convex insect superficially resembling the Endomychid 
genus Micropsephus. Delphastus, Casey, of the group 
Oenini, seems to be related to Lnoscymnus. 
*Tioscymnus diversipes, n. sp. (Plate IV, figs. 4, 4a, b.) 
Very convex, shining, black, the antennae, mouth-parts, and legs 
flavo-testaceous, the under surface of the head, the pro- and meso- 
sternum, and the ventral segments testaceous or rufescent, the 
head in one specimen testaceous in front. Head and thorax 
sparsely, very finely punctate, the elytra almost smooth. Beneath 
minutely punctulate. €
