50 PROCEEDINGS OF THE NATIONAL MUSEUM vol.65 



Originally described by Olivier (1790) from Guadeloupe, and is 

 recorded from the same locality by Fleutiaux and Salle (1890). 

 Castelnau and Gory (1837), and also Kerremans (1910) record it 

 from Cayenne, French Guiana, without refering to the type locality, 

 which they have probably overlooked. No specimens have been seen 

 which would apply to the description given for this species. Kerre- 

 mans ^^ records a specimen of Psiloptera variolosa Fabricius from 

 Guadeloupe in the Paris IMuseiim, which probably is this species. 



PSILOPTERA (LAMPETIS) GUILDINI Castelnau and Gory 



Psiloptera guildini Castelnau and Goky, Mon. Bupr., vol. 2, 1837, Bvprestis, 

 pp. 41-42, pi. 10, fig. 51. — Kebremans, Mon. Bupr., vol. 5, 1910, p. 144. 



Form broadly elongate, attentu'ate and broadly rounded in front, 

 more acuminate posteriorly; elytra without marginal grooves; sur- 

 face uniformly blue or bluish-green above and beneath; tarsi vio- 

 laceous. 



Head nearly flat; occiput with a narrow longitudinal groove; 

 surface strongly and veiy irregularly rugose, the elevations broadly 

 convex, irregular in size and shape, covering the entire surface, and 

 densely, rather coarsely granulose, the depressions coarsely, sparsely 

 and irregularly punctate, and from each puncture arises a short, 

 erect hair; epistom'a broadly and rather deeply arcuately emargi- 

 nate at the middle, with an obtuse tooth on each side of the emar- 

 gination. Pronotum about one and three-fourth times as wide as 

 long, distinctly narrower in front than behind, widest along basal 

 third; sides strongly obliquely expanded from anterior margin to 

 basal third, then ne'arly parallel (feebly sinuate) to the posterior 

 angles, which are acute; anterior margin nearly truncate, with only 

 an obsolete median lobe; base bisinuate, with a very broad, moder- 

 ately rounded median lobe; lateral margins rounded in front and 

 feebly crenulate posteriorly ; surface regularly convex, without trans- 

 verse or longitudinal elevations, feebly impressed in front of scutel- 

 lum, coarsely and irregularly punctate, the punctures deep, and 

 becoming somewhat confluent toward the sides; intervals finely 'and 

 densely granulose. Scutellum very small, transverse, and finely 

 granulose. Elytra slightly wider than pronotum at base, feebly 

 expanded behind the humeral angles, which are obtusely angulated. 

 par'allel to apical third, then arcuately attenuate to the tips, which 

 are truncate and feebly emarginate; lateral margins entire, or at 

 most, only obsoletely crenulate near humeral angles; surface striato- 

 punctate, the striae feebl}' impressed, and the punctures rather 

 coarse and distinctly separated, intervals feebly convex and obsolete- 

 ly granulose, the striae and intervals are interrupted by numerous
