merous punctures paralleling anterior emargination; both lobes 

 laterally with abundant, crowded punctures. 



Scutellum: Wider than long, 4.10(4.00-4.33) :3.87(3.83-3. 91) ; with 

 numerous punctures from base to near apex, these irregularly crowded, 

 forming transverse ruga between them. 



Propleuron and mesopleuron: As in generic description. 



Metapleuron: As in generic description, without impressed line 

 extending laterally from apex of peritremc.

 punctures laterally, apical margin broadly and shallowly U- or V- 

 emarginate; gonostylus as illustrated (fig. 202). 



Length of body: 13.08(12.57-14.03). 



Female : Similar to male but posterior margin of sternite VI with 

 a shining, subapical, transverse flattened area (fig. 202), and measure- 

 ments usually averaging distinctly larger than those of male. 



Head: Length-width ratio, 2.02(1.95-2.05) :2.99(2. 95-3.08); inter- 

 ocular width, 1.64(1.62-1.69). Antennal segments: I, 0.55(0.42-

 (2.00-2.23); III, 1.85(1.60-2.16); IV, 1.23(1.16-1.36). 



Pronotum: Length-width ratio, 3.49(3.33-3.61) :6. 80(6.30-7.09). 



Scutellum Length and width subequal, 4.27(4.08-4.35) :4.28(4.06- 

 4.35). 



Terminalia: Ventral genital plates flat to gently concave. 



Length of body: 13.83(13.41-14.23). 



Type data.^ — Dr. Sailer reported that a Uhler spechnen (USNM) 

 labeled "Teffe" bears a determination of Ectinopus rugoscutum in v/hat 

 appears to be in Signoret's handwriting. It agrees with the original 

 data and may be designated lectotype.

Genus Onalips Signoret 



Onalips (in part) Signoret, 1881b, p. 323. 



Signoret originally described Onalips for two species, Aethus 

 nigerrimus Dallas (1851) and Onalips cribratus. Examination proves 

 that these two are not congeneric. Therefore Onalips is here restricted
