CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 545 



Scutellum: Little longer than wide, 1.85:1.75; surface shining, 

 disc with numerous close-set punctures coarser than those of pronotum, 

 apex with fine punctures; apex broadly angled, more than half as 

 wide as membranal suture. 



Hemelytron: Corial areas well defined, alutaceous; exocorium more 

 closely punctured than disc, latter with a single row of close-set 

 punctures; paralleling claval suture; clavus alutaceous, with two 

 longitudinal rows of punctures; costa with ten or twelve setigerous 

 punctures; membranal suture strongly bisinuate (fig. 81), lateral angle 

 acute; membrane longer than basal width. 



Propleuron: Finely alutaceous, impunctate; prosternal carinae 

 thick, prominent, abruptly and acutely terminated ventrally, area 

 between depressed. 



Mesopleuron: Evaporatorium triangular, extending about three- 

 fourths across segment, and separated from posterior margin of seg- 

 ment nearly to base by polished area. 



Metapleuron: Evaporatorium reaching three-fourths across seg- 

 ment, lateral tw^o-fifths more shining; peritrem.e abruptly terminated 

 before middle of segment. 



Legs, abdomen and terminalia: All missing. 



Length of body: About 5.5. 



Type data. — The author has been unable to locate Signoret's 

 type, reported as having come from Chile. 



Specimen studied. — A broken specimen (USNM) of unknow^n 

 sex, reported from Chile. 



Discussion. — The specimen (USNM) studied was old and incom- 

 plete, lacking antennae, legs, and abdomen. It bore an unusual, 

 double-spaced, blue-bordered label with a determination of "Aethus 

 blanchardi" in what appeared to be Signoret's handwriting, and a 

 penciled note, "Chile." This specimen may have been a part of the 

 Uhler collection, although it was not so labeled. 



In illustrating this species in his "Revision," Signoret (1882) 

 depicted the peritreme as terminating in an auricular lobe. The 

 specimen at hand showed the peritreme ending abruptly, but not in 

 the loop or ear-shape structure implied by Signoret.

Diagnosis.— The large size (9.5-10.2) plus the strongly alutaceous 

 coria wdll differentiate this species from all others in the genus. 



Description. — Male: One specimen. Elongate-oval. 



Head: Length more than two-thirds width, 1.75:2.34; interocular 

 width, 1.52; outline semicircular, juga narrowdng clypeus or contiguous 

 beyond it; clypeus without subapical punctures; juga roughened by
