46 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 123 



Remarks: The coloring of this species, of which only the type has 

 been seen, differs from the coloring of G. monrosi Blake and G. pin- 

 nigera Blake in that the prothorax is deep reddish brown and the 

 elytra have a distinctly aeneous-green lustre. Iu addition, the shape 

 of the elytra is different in being more tapering, with a suggestion of 

 a prolongation at the tip. The drawing of the type at the British 

 Museum unfortunately was made on a smaller scale than for the rest 

 of the species. The beetle, measuring about 7 mm., is comparable 

 in size with G. monrosi and G. pinnigera. 



Glyptoscelis gayi Lefevre 



Figure 39 

 Glyptoscelis gayi Lefevre, 1891, Ann. Soc. Ent. Belgique, vol. 35, p. 270. 



Between 8 and 9 mm. in length, oblong oval, shining black, pro- 

 thorax densely and deeply punctate, without median bare line, elytra 

 with very strong horizontal ridges, white pubescence on upper 

 surface not dense or obscuring surface. 



Head with interocular space more than half width of head, head 

 coarsely and densely punctate, the suture about lower front separat- 

 ing it from upper front very indistinct, a fine white pubescence, 

 labrum reddish brown. Prothorax strongly convex with lateral 

 sides only slightly curved, widest at base, slightly wider than long, 

 surface densely and deeply punctate with coarse round punctures 

 over all, no median bare line, the white pubescence fine and not 

 obscuring surface. Scutellum black. Elytra with deep intrahumeral 

 sulcus, neither depressed nor elevated behind scutellum; surface 

 very rugose with strong horizontal ridgings between rows of punc- 

 tures, along side near apex a more or less distinct costa, which at 

 apex unites with a vague subsutural apical costa in a small knobby 

 prominence; pubescence fine, white, not obscuring surface. Body 

 beneath with much heavier white pubescence, legs reddish brown. 

 Length 8-9.5 mm.; width 3.5-4 mm. 



Type: In Museum of Natural History, Paris. 



Type-locality: "Chili (Santa Rosa)." 



Other localities: Chile: Serena, Coquimbo, Illapel. 



Remarks: The drawing of this species was made from a specimen 

 from the Monr6s collection bearing the label "Glyptoscelis Gayi Ed. 

 Lef. Auct. det. 1894." The locality is simply "Chili Gay." It is 

 undoubtedly authentically determined. There are four specimens 

 in the Frey Museum. These are the only ones examined by the 

 writer. The species is distinctive because of the strong horizontal 

 ridgings on the elytra, which are stronger than in any other species 

 of the genus. The aedeagus is unusual in its long narrow tip. The 

 punctation of the prothorax is deep and close.
