AUT 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 77 



Allotype (female). — Black: extreme apical, lateral angles of 

 clj'peus; spot below on scape; spot on either side anterior ocellus; 

 obscure yellow. Posterior orbits not reaching vertex; narrow line 

 below tubercle on prothorax; fascia narrowed laterally on posterior 

 surface of propodeum; lateral angles of propodeum; broad fascia on 

 first tergite with broad, shallow, median anterior emargination; 

 fascia on second tergite inclosing a pair of elliptical dorsal black 

 .-pots; small lateral spots on second sternite; femora apically in part; 

 anterior surface of anterior tibiae ; outer surface of middle and pos- 

 terior tibiae; hnght creamy yellow. The yellow of the tarsi is ob- 

 scured by brownish or ferruginous. The posterior surface of the 

 anterior metatarsus, as in the type, is black. The sixth tergite is 

 bluntly rounded at the apex. The sixth sternite bears numerous 

 coarse punctures, especially near the apex, among which are many 

 very fine punctures. The second sternite is slightly carinate on the 

 midline, shining and provided with scattered coarse punctures. 



The wings in this species are hyaline and the pubescence is very 

 ?hort and inconspicuous. The posterior lateral angles of the propo- 

 deum are unusually prominent in this species, giving the posterior 

 surface of this segment somewhat the shape and appearance found in 

 the genus Bicyrtes. 



I have assigned to this species two other males that differ markedly 

 fi'om the type in the extent of their maculations. On each of these 

 the labrum is wholly yellow; the clypeus bears only a small pair of 

 black spots; the prothorax is almost wholly yellow; there are lateral 

 spots on the scutellum, a fascia on the metanotum, a curved fascia 

 on the propodeum, and a small spot on the mesopleura. On one there 

 are broad fasciae on the first six tergites, the second inclosing black 

 spots, whereas on the other the fasciae are limited to the first three 

 tergites, the second fascia inclosing black spots. I have placed these 

 specimens in this species in spite of the fact that they differ go 

 widely in the extent of their maculations and are slightly larger in 

 size, because I can find no essential difference in the morphological 

 characters of the three males and because no two of them agree in 

 the extent of their maculations. 



Length, 22 mm. Described from three males and one female. The 

 type ^ and allotype are from Neu-Kamerun, collected by Tessmann. 



5 Tlio specimen designated as the type of this species is in bad condition. When received 

 for study the sixth and seventh abdominal segments were completely retracted so that 

 the specimen had to be relaxed before it could be studied. At some previous time it had 

 decoiiipo.>--ed to such an extent that not only ha.«i the color faded but as soon as it was 

 relaxed it fell into pieces and had to be reassembled after the genitalia had been extracted 

 and the terminal abnominal segments extended. After the description had been written 

 the genitalia of the type, through an unhappy accident, was lost, but not before the 

 author had made a careful comparison of the genitalia of the type and paratypes and 

 assured himself that there were no differences between them di.scornible.
