9. 8 mm. Head. — Face as in diadenui, front longitudinally depressed below 

 the an teiior ocellus ; no malar space present. 



Thorax. — Pronotum seen from aliove presents three lateral points, the middle 

 one most pronounced, a depression filled with pubescence is piesent in the mid- 

 dle of the pronotum; mesonotum witli visible but rather indistinct parapsidal 

 grooves, punctures in the space between the parapsidal gi'ooves smaller and closer 

 than those on the parapsides; sculi)ture of mesopleura hidden by appressed sil- 

 very pubescence ; posterior lateral corners of scutellum and sides of postscutellum 

 as in dindema, process of the postscutellum a little broader at apex than at base. 



Abdomen. — Segments with a shar|)ly defined depressed margin ; first segment 

 visibly depressed in three places, the median depression deepest, no longitudinal 

 smooth space, punctures large and separated, the margin or apical fourth of the 

 segment i-ugulose, the sculpture nearly hidden by pubescence; segments two and 

 three with the apical third rugulose and covered by pubescence, base of these 

 segments with small punctures, medially with large punctures, apical third of 

 third segment covered with dense jmbescence, the margin testaceous and with 

 about sixteen strong spines.

% . 10.5 mm. Head. — Face bare, depressed to form a shallow smooth polished 

 basin ; front jjunctui'ed as strongly as the vertex and cheeks ; no malar space. 



Thorax. — Pronotum seen from above presenting an anterior and posterior lat- 

 eral point, only a slight median depression anteriorly; parapsidal grooves on the 

 mesonotum visible but not distinct, the punctures on the surface between them 

 smaller and closer together than those on the parapsides; mesopleura bare or 

 nearly traversed obliquely by a shallow channel ; posterior lateral corners of the 

 scutellum and sides of the postscutellum not densely pubescent ; process of the 

 postscutellum broader in the middle than at base or apex. 



Abdomen. — The depressions on the anterior face of the first abdominal segment 

 not very distinct, no long smooth space, punctures large and adjoining, depressed 

 margin not sharply defined, nor is the nearly rugose sculptured area hidden by 

 pubescence; second and third segments like the first; fourth segment with a 

 black margin bearing about eleven strong spines, rounded at apex, not triangular 

 in outline.
