[March 
where there are also some smooth areas. Lower metapleuron: with 
uniform, coarsely reticulate wrinkling; juxta-coxal carina not de- 
fined. Front tibia: moderately inflated. Flind trochantellus: 0.57 
as long as its trochanter in dorsal view. Third hind tarsomere: 
ventrally with about 8-9 strong spines (in addition to the apical 
group) which are not arranged in regular longitudinal rows. Pro- 
podeum: spiracle 1.5 as long as wide; cristae large and strongly 
projecting short ligulate, about 1.1 as long as wide at base, apical 
carina weakly defined and gently arched forward between them; 
dorsal face behind basal trans-carina with rather coarse, irregular 
but not much reticulate wrinkling; the apical face centrally with 
strong longitudinal wrinkling, becoming smooth sublaterally and 
then transversely wrinkled laterad. First gastric ter git e: postpetiole 
1.4 as wide at apex as long from spiracle to apex; gently arched in 
profile. Second gastric tergite: smooth and highly polished with a 
few tiny, very sparse punctures. Ovipositor: sheathed portion 0.43 
as long as fore wing; tip 0.20 as high at nodus as long from nodus 
to apex, weakly sagittate with a direct taper between nodus and 
apex. 
MALE: Unknown. 
TYPE: In collection of Dr. Henry K. Townes, 5950 Warren Rd., 
Ann Arbor, Michigan, 48105. 
RELATIONSHIPS: The polished second gastric tergite, nasute cly- 
peus, and rather strong subconic projection anteriorly on the hu- 
meral margin of the pronotum suggest affinity with C. compacta, 
to which vallis runs in Townes’ key to the North American Crypt- 
anura (1962, p. 427). However, compacta differs from vallis in 
many chromatic and structural features of which those not already 
mentioned in my foregoing key are summarized below: 
Mesopleuron black on lower 2/3 except for a broad, oblique 
white area extending from prepectal carina to lower hind corner 
but not invading speculum or approaching mesopleural suture ex- 
cept far below; propodeum black with a very broad white stripe 
on each side reaching rearward from basal trans-carina across 
crista to hind margin; fore and mid femora broadly black above; 
hind coxa pure white with an almost percurrent broad black stripe 
dorsally and with other black markings; hind femur black with 
yellow anteriorly and posteriorly; dorsal margin of pronotum very 
strongly swollen and produced anteriorly into an exceptionally 
prominent broadly conical projection; prepectus opposite lower
