Cyrtomenus (Cyrlomenus) bergi, new name 



Plate figure 243 

 Cyrtomenus ciliatus Berg, 1879, p. 10 (nee Palisot de Beauvois, 1805, p. 186). 



Diagnosis. — The smaller ocelli which are separted from the eyes 

 by a space slightly greater than a transverse ©cellar width or the 

 absence of strong rugae on the head will mark this species as distinct 

 from the other three in the subgenus. 



Description. — Male: Head: Length more than half width, 1.45 

 (l.ll-1.62):2.08(1.71-2.47);interocularwidth, 1.34(1.10-1.50); anteri- 

 or outline nearly or quite a full semicircle, juga surpassing and converg- 

 ing or contiguous in front of clypeus; surface polished, with weak to 

 obsolete, radiating rugae, impunctate, with minute punctures or with 

 few distinct punctures anterior to ocelli; ocelli small to moderate, 

 separated from eye by space little greater than transverse ocellar 

 width; jugum ventrally weakly alutaceous, sometimes with few small 

 punctures; maxillary plate strongly alutaceous and with crowded 

 punctures. Antcnnal segments: I, 0.47(0.34-0.03); II, 0.27(0.20- 

 0.43); III, 0.47(0.35-0.63); IV, 0.47(0.40-0.53); V, 0.49(0.46-0.90). 

 Bucculae about half as high as labial II; labium slightly surpassing 

 apices of intermediate coxae. Labial segments: I, 0.78(0.53-1.06); 

 II, 1.02(0.70-1.40); III, 1.02(0.70-1.40); IV, 0.77(0.57-1.03). 



Pronotum: Length more than half width, 2.58(1.82-3.00) :4. 63 

 (3.57-5.46); lateral margins straight on basal half, with submarginal 

 row of 15 to 20 setigerous punctures; transverse impression weakly to 

 moderately impressed, obsolete or absent at middle, marked by 

 irregular, interrupted row of coarse punctures; anterior lobe with 

 weak subapical impression, with several coarse punctures laterally 

 and in subapical band; posterior lobe with few to many coarse scat- 

 tered punctures medially. 



Scutellum: Length less than width, 3.01(2.26-3.60) :3. 07(2. 25- 

 3.73); disc with widely scattered, sunken, coarse punctures. 



Hemelytron: Clavus and corium polished; clavus with one row of 

 punctures medially; mesocorial punctures arranged in two rows 

 paralleling claval suture, outer row often incomplete, discal punctures 

 numerous, well-separated, often absent along radial vein; exocorium 

 usually more sparsely punctate than mesocorium; costa with six to 

 eight setigerous punctures; membrane distinctly surpassing apex of 

 abdomen. 



Propleuron: Variable, from polished and impunctate to roughened 

 by crowded, fine, longitudinal rugulae and small punctures. 



Mesopleuron: Lateral area shining, impunctate, with few oblique 

 rugae. 



Metapleuron: Lateral area polished, impunctate.
