BATRISINI 235 



in Group VI and the latter in Group VII. The male bruchi is described as 

 having the vertex deeply and transversely impressed, and this feature with the 

 simple, uncarinated tempora and normal antennae would place bruchi in 

 Syrbatus Group II if the pronotum is Syrbatus. 



Group III 



Vertex with a semicircular patch of squamous pubescence just above 

 (mesiad) of each eye, these areas sharply defined and conspicuous 



so as to give the impression of a double eye each side; 2.1 mm 



quadrioculatus 



Vertex not as above 2 



2. Clypeus with either a strong obtuse carina or an elevated tubercle ... 3 

 Clypeus not carinate or tuberculate 4 



3. Clypeus with a strongly developed obtuse median, longitudinal carina ; 



clypeus excavated on each side and apically in the form of a pointed 



arch (ogival) ; 1.8 mm sublaminatus 



Clypeus excavated each side near base and medianly an elongate tu- 

 bercle which is flattened on top and may be described as an "ele- 

 vated plaque", squamous; 2 mm scitus 



4. Clypeus prominent, wholly concave with a ciliated margin; 1.7-1.8 



mm curvispina 



Clypeus prominent, flattened and ogival in form (that is acute- 



pyriform or in the form of an apically pointed arch) ; 1.7 mm 



phantasma 



Group IV 



Intermediate trochanters dilated and truncate, with a brush of short 

 setae; 1.6-1.7 mm calcarifer 



Intermediate trochanters each with a strong tooth or spur at apex; 

 2.3 mm simpUcifrons 



Also in this group belongs marthae Reitter, but described on the female 

 sex only; 1.7 mm. long, and said by Raff ray to closely resemble calcarifer 

 Reitter. 



Group V 



First antennal segment simple, not abnormally large or irregularly 



dilated mirabilis 



First antennal abnormal, large, irregularly dilated 2 



2. Pronotum abruptly narrowed apically so that the apical angles are 



accentuated, and the sides only slightly rounded in contour to nearly 



straight 3 



Pronotum gradually narrowed apically so that the apical angles are 

 obsolete and the sides arcuate 8 



3. Clypeus with apical margin square and truncate 4
