4 PROCEEDINGS OF THE NATIONAL MUSEUM vol.76 



National Museum, and these are the only ones I have seen, as the 

 species was not represented in the collection before. These have also 

 been compared with the types by Mr. Banks. 



The character used by Mrs. Phillips in the very beginning of her 

 key to Cecidochares, of the lower frontal bristles being remote from 

 the edge of the eye, does not apply to the specimens received from 

 Banks; the whole paragraph leading to polita in this key applies to 

 gibha more than to any other species known to me, and this I have 

 placed in a new genus. 



The Banks specimens of polita have yellow legs, head yellow except 

 the upper back part; no anterior dorsocentral; the pale flattened hairs 

 of the mesonotum leave two rounded bare polished black spots on 

 each side, before and behind the suture; the pleurae are shining black 

 anteriorly and below, but with a delicate pruinosity extending back 

 from the middle of the pteropleura and covering the metanotum more 

 densely. The middle of the mesonotum is slightly pruinose from front 

 to back, with two rows of acrostichal pale hairs in front, separated 

 from a single row in line with the dorsocentrals. The brown pattern 

 of the wing is tinged with yellow except on its borders and the whole 

 of the basal spot. 



PROCECIDCCHARES MONTANA Snow 



Oedaspis montana Snow, Kansas Univ. Quart., vol. 2, 1894, p. 163, pi. 6, fig. 5. 



The only specimen heretofore recorded is the single male type, 

 from Montana, which I am permitted to redescribe. The species is 

 not represented in the National Museum. It is like polita and penel- 

 ope in having the femora yellow, but separates readily by the characters 

 of the key. It differs from both in having a smaller eye, the cheek 

 being three-tenths of the eye height; in polita it is two-sevenths, and 

 in penelope it is three-sixteenths. The vertex in montana is 0.50 of 

 the head width, and in penelope 0.40; while the available specimens 

 of polita being a little shrunken are not in condition to measure. The 

 parafacials in montana are obviously wider than in either of the others, 

 but difficult to measure. 



Head yellow except for upper occiput. Thorax and abdomen black 

 in ground color, the former with a distinct scar of the presutural dor- 

 socentral on one side, the other side too much damaged to show it. 

 Mesonotum considerably rubbed, but apparently with fewer pale flat- 

 tened hairs than in most of the species; the roundish polished spots 

 very shining, a pair before and a pair behind the suture. Scutellum 

 badly damaged. Pleurae distinctly pollinose over their whole surface, 

 a good mark. Abdomen also opaque, covered with white hairs, no 

 black ones at all. Wings with yellowish pattern of three bands and 

 a basal spot, as usual, but the apical band is short and oblique, and 

 connects with the preceding between the second and third veins
