elusions which Burr has reached, discussing these in the present 
paper under that heading. 
The Championi Group of the Genus Labia 
The species of the present group are slender and very small, 
the males having the forceps unarmed, weakly angulate-arcuate, 
and the area embraced by them consequently elongate and 
roughly ovate. From the original descriptions we are able to 
associate championi Bormans, tristani Borelli and equatoria Burr, 
all closely related species. A fourth species is here described. 
Labia micans new species (Text fig. 2; plate XXVI, figs. 3 and 4.) 
The present species shows nearest relationship to L. tristani, 
differing in the smaller size, slightly different male forceps and 
male pygidium, which in that species differs in being “. . . 
quadrangolare, all’incirca largo quanto lungo, appiattito. ...” 
In L. championi decided differences are found in the unicolorous 
pronotum and very strongly transverse male p 3 ^gidium. 
The character of the antennal annulation is probably" the same 
in all of these species, the distal joints being pale, their number 
varying individually. The presence or absence of wings which 
show beyond the tegmina, is evidently also a feature of individual 
difference!^ and not diagnostic, as was also supposed by Borelli.!^

Busek.) [U. S. National Museum.] 
Size very small, form slender. Head smooth, shining, convex, with sutures 
indistinct. Eyes small, distinctly shorter than cheeks. Antennae (with twelve 
and thirteen joints) ; first segment large, as long as second and third together, ex- 
panding slightly near base, thence with sides parallel; second minute; third 
elongate; fourth three-quarters as long as third; fifth nearly as long as third; 
succeeding joints increasing slightly in length distad, ovate, the longest slightly 
more than tvdee as long as broad. Pronotum smooth, with a single bristle 
at each cephalic angle; length subequal to greatest (caudal) width; lateral 
margins feebly cingulate, nearly straight, very feebly diverging to the sharply 
rounded, nearly rectangulate caudal angles, caudal margin very feebly convex; 
median portion of surface weakly convex, triangular, with apex truncate at 
caudal margin of pronotum, remaining narrow lateral portions deplanate. 
See Burr, in considering Prolabia unidentata, Proc. U. S. Nat. Mus., xxxviii, 
p. 4.51, (1911). We fully agree with these observations, which are borne out 
by a single female, with wings well produced beyond the tegmina, in the present 
.series of micans.
