to the apex ; intermediate surface finely, sparsely pianctate, and covered 

 sparsely with moderate pointed yellow scales. Pijgiclium slightly wider than 

 long, triangular ; sides equally arcuate ; surface feebly convex, slightly im- 

 pressed at the sides, sparsely clothed with elongate whitish scales which are 

 dense along the base, and much sparser in a very narrow median line ; surface 

 also very sparsely and finely pubescent. Abdomen with small robust whitish 

 scales, much denser along the apical margins of the segments, and also with 

 very sparse erect pubescence. Length 36.0 mm. 



Colorado (exact locality unknown — 9 ) ; New Mexico — % . 



This fine species is easily clisting-uisbahle by its antennal structure 

 from any other in the genus. The last joint of the maxillary palpi 

 is very feebly lunate, and is pointed at apex. The anterior tibige 

 are robust, the outer teeth strong, the one nearest the base very 

 broad, obtuse, and feebly developed.^ 



1 I take the present opportunity to describe an interesting new species, 

 received a short time since from Central America. The description refers to 

 the female. 



P. COllClirrens n. sp. — Form nearly as in decemlineata, pale brownish- 

 rufous. Clypeus truncate, broadly arcuate in the middle ; angles right, not 

 rounded, but also not prominent, its surface feebly and very narrowly reflexed 

 at the apical margin, having a few widely scattered, coarse, squamigerous 

 punctures ; front immediately behind the suture abruptly, coarsely, extremely 

 densely and deeply punctate, the punctures in mutual contact, the occiput 

 again abruptly totally impunctate ; antennse moderate, club as long as joints 

 two to four combined ; sixth joint rather less than one-half as long as the 

 remainder, which are equal. Piothorax nearly as in decemlineata, but very 

 much more sparsel}- punctate, the median line very deeply impressed, and the 

 vittse narrow ; scales large and robust. Scutellum polished, with a narrow 

 median vitta. Ehjtra with ten very narrow, densely squamose vittfe, the 

 second from the lateral margin long, extending to apical third, but very widely 

 interrupted ; intervals extremely sparsely squamose, the scales smaller and 

 narrower than those of the vittfe. Length 25.0 mm. ; width 11.0 mm. 



Honduras. (One specimen.) 



Although resembling decemlineata, this species is smaller, less robust, and 

 differs greatly in the form of the pygidium, which is slightly longer than wide, 

 transversely convex, and extremely sparsely squamose, a narrow median line 

 entirely glabrous. The anterior tibise are tridentate, the basal tooth veiy 

 broad and feebly developed. The front and vertex in this species, and also 

 in speciosa, are very much more densely and coarsely punctate than in decern- 

 linenta, where the punctures are separated by their own widths. All compari- 

 sons have been drawn from the female, which is the more constant sex.
