114 Mr. G. ©. Champion’s Notes on 
short joint may be present. The type is a minute insect 
superficially like an Atomaria. 
*Pseudevolocera atomarioides, n. sp. (Plate ITI, 
figs. 16, 16a.) 
Ovate, convex, shining, obscure ferruginous, the elytra infuscate 
and subalutaceous, the antennae and legs testaceous; the surface 
above and beneath not visibly punctate. Thorax with an abrupt 
deep basal groove extending across more than half its width, but 
without trace of foveae. Antennae with joints 2 and 3 elongate, 
3-7 slender, 4 and 5 apparently longer than broad, 6 and 7 trans- 
verse, the club (8-10) with the last two joints strongly transverse. 
Length 1$ mm. 
Hab. GUATEMALA, Cerro Zunil, 4,000 feet, Pacific slope 
(Champron). 
Two specimens. The less dilated, non-foveate thorax 
and the smooth surface separate P. atomarioides at once 
from Evolocera champiom, Sharp,which also is an inhabitant 
of Guatemala. 
LYCOPERDINELLA, Nn. gen. 
Antennae (fig. la) 10-jointed, 1 and 2 stout, subcylindrical, 3-9 
obconic, decreasing in length, 10 dilated into a very large triangular 
club; terminal joint of the maxillary palpi narrow; head subtri- 
angular, deeply sunk into the prothorax, the labrum and epistoma 
transverse, the antennae inserted immediately before the eyes, 
which are reduced to four or five facets ; prothorax largely developed, 
sharply margined, strongly plicate on each side behind, and deeply 
transversely sulcate before the base ; scutellum small ; elytra acumin- 
ate-ovate, with a deep sutural stria and extremely narrow and 
incomplete epipleura; prosternum well developed in front of the 
anterior coxae, the sutures sharply defined, the intercoxal pro- 
cess narrow and parallel-sided; metasternum rather long, the 
episterna moderately broad; ventral segments 2-5 subequal in 
length, the sutures straight ; legs long, the femora clavate, the tibiae 
narrow, the tarsi slender, 3-jointed, joint 1 longer than 2, 3 elongate ; 
body oblong-ovate, convex, setose. 
Type, L. subcaeca. 
This interesting genus must, I think, be included in the 
subfamily Merophysiinae of the Lathridiudae, near Holo- 
paramecus. It has the facies of a miniature Lycoperdina.
