imens often reddish brown) with reddish brown legs. It has def- 

 inite, long, deep lateral grooves but the narrow posteromedian 

 groove is vague or obsolete and the paramedian grooves, if present 

 at all, are even more vague. The scutal punctations are distinctive, 

 being of a imiformly shallow, small or medium size, densely and 

 closely distributed in irregtilar lines everywhere except in the 

 scapular areas, on the festoons, outside the lateral margins, 

 and in a narrow area just inside the lateral margins; most punc- 

 tations are clean and discrete. Shallowness of punctations varies 

 among individuals, but the pits are never deep and are sometimes 

 quite superficial. The overall appearance is one of rej^arity 

 of punctations within the impunctate periphery bordering the 

 lateral grooves; no pattern of larger and deeper punctations is 

 visible among the normal punctations. If the punctations are 

 exceptionally shallow, those in the area of the posterior grooves 

 tend to be slightly larger and deeper than elsewhere. Coxa I has 

 a stump showing dorsally, but no dorsal process. In engorged 

 specimens, the three median festoons protrude. The adanal shields 

 of typically large specimens are sickleshaped, with a deeply cxirved 

 inner margin, but in smaller specimens this feature may be con- 

 siderably reduced (at the moment, I woiild not know how to dis- 

 tinguish runt specimens with narrowly elongate, xoncurved adanal 

 shields from small specimens of R. capensis ). 



Female ; This sex (which, so far as known, cannot be dis- 

 tingxiished from R . capensis ) has a subcirciilar scutum densely 

 beset with uniform, fairly large punctations very much like those 

 of the male, but usually somewhat larger, deeper, and more dense; 

 these punctations are evenly distributed in the depression within 

 the lateral grooves but are sparse or almost entirely absent in 

 a narrow area along the posterior margin and on the elevated 

 ridge outside the lateral margins. 



Note ; A male and a female cotype of R. falcatus examined 

 in British I'^useum (Natural History) collec'^ions conform to the 

 description of typical specimens of R. longus as provided above.
