14 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 120 
Discussion: Bedford (1920) gave the following measurements (inmm). 
male female 
length of head 0.25 0.33 
width of head 0.53 0.60 
width of prothorax 0.38 0.43 
width of metathorax 0.55 0.71 
width of abdomen 0.85 1.15 
total length 1.74 2.36 
Except for females being larger in abdominal width and total length, 
these measurements fall within the ranges of Chapinia lophocerus 
(tables 1, 2). ©. lophocerus resembles most closely C. fasciatt. 
The venter of the third femora and posterolateral margins of abdominal 
sternites [V—-VI each have small scattered brushes of normal setae in 
C. lophocerus, C. fasciati, and C. camuri but large thick brushes of 
normal setae in C. bucerotis. Abdominal sternite II of both sexes 
has fewer than 58 total setae and one median row of setae in C. 
lophocerus, C. fasciati, and C. camurt but more than 58 total setae 
and three median rows of setae in C. bucerotis. ‘The male genitalia 
have each lateral horn possessing posterior points that do not reach 
the slender endomeres in C. lophocerus, C. fasciati, and C. camuri but 
one sharp point that crosses the broad endomeres in C. bucerotis; 
the posterior two points are sharp in C. lophocerus but rounded in 
C. fasciati, and there is only one rounded posterior point in C. camurt. 
The ventral sclerite between female vulva and anus is not elevated 
medially between the sclerital hooks in C. lophocerus, is elevated 
slightly in C. camurt, but is more elevated in C. fasciati and C. bucerotis. 
The female anal fringe has fewer than 58 setae in C. lophocerus, at least 
72 setae in C. fasciati, and 58-72 setae in C. camuri and C. bucerotis.
