apices conjointly rounded. The suture is elevated posteriorly, costae three 

 in number, arranged thus : first nearly straight, parallel to the suture, 

 reaching the base but abbreviated at apex ; second parallel to the first, 

 slightly shorter at each end ; third forming an overhanging margin to 

 elytron, until it reaches a point just beyond the tip of the second, when it 

 curves in and becomes discal, but fades out before attaining the elytral 

 apex. None of the cost?e are confluent at any point. Body beneath with 

 large scale-bearing punctures, distant on the abdomen, but more approxi- 

 mate on the thoracic segments. Legs densely scaly and comparatively 

 stouter than in anastomosis. Length, 9 mm. 



This beetle can be separated from O. anastomosis at a glance, the 

 thoracic characters alone being amply sufficient for its differentiation, while 

 the elytra are unlike those of the former species in shape as well as in 

 ornamentation. From the antennae alone, one might doubt the propriety 

 of the generic reference, but the deflexed apex of the presternum excludes 

 the insect from Astrotus. The type was taken in Cameron Cotmty, Texas, 

 during the month of September, by Frank B. Armstrong. 



Pyrota, Lee. 



Several years ago I received specimens of a beetle belonging to the 

 above genus, which, by its antennal characters, approaches CantJiaris, 

 recalling in its general appearance C. bigutaita, though, of course, not to 

 a deceptive degree. After a study of the material, I concluded that the 

 species was undescribed, and wrote to Dr. Geo. H. Horn, asking 

 his opinion. This coincided with my own, and as the insect seems 

 to have been taken in some abundance, and is probably represented 

 in numerous collections, I projiose to name it after the State in which it 

 occurs. 



F. Dakotana, n. sp. — Elongate, head and thorax shining, elytra 

 much less so. Above yellow, thorax with two small blackish discal spots, 

 one on each side of the middle line ; elytra each with a narrow, nearly 

 straight longitudinal blackish stripe, which does not reach the apex nor 

 the base, and is somewhat more distant from the suture than from 

 the lateral margin. Head yellow, sjjarsely, irregularly and rather coarsely 

 punctured ; sides behind the eyes almost exactly parallel for a short 

 distance ; hind angles broadly rounded. Antenna? shorter and stouter 

 than usual, blackish, first joint paler at base, third joint longer than the 

 fourth. Palpi blackish. Thorax cam])anulate, widest behind the middle, 

 sides rounded, less so anteriorly, where they are rapidly convergent; basal
