Show s, .L, Ill., ow, ANew Weevil in the Genus Dyslobus Study No. IP ·M. -JI, By VASCO M. TANNER m. -, In using Dr. Van Dyke's synoptic table, 1933, p. 31, of the genus Dyslobus studying species of this genus collected in Utah, I was unable to determine satisfactorily the species described in this paper. I then began a study of the genitalia of species in this genus and related genera and found that this species was distinctive from all other species in my collection and from other species reviewed by Dr. Van Dyke in his table. I therefore take this oppor tunity of describing this species as new, giving it the name of wasatchensis, in because of its occurrence in the Wasatch range of Utah. Dyslobus wasatchensis Tanner, new species long Holotype a female, Fig. 1: from oval to elongate, more than twice as female robust, male slender, body color black, but covered as wide, throughout with chocolate, white and golden colored roundish squamae which cover small pited tubercles, and with golden lance-shaped decumbent hairs which arise in small punctures scattered among the tuber cles. This gives a uniform appearance over the head, thorax, elytra and femora, except around the scrobes The and the mouth parts where it is rugulose. whitish squamae are so distributed as to give a flecked The vertex of the head is smooth with appearance. small punctures; the eyes are small, black and scarce ly protruding beyond the sides of the head; the ros trum is less than twice as long as wide, with a slight ridge in the middle portion. The antennae are thick ly covered with decumbent hairs, the scape reaching only to the first third of the eye; the funicular seg ments are, first and second elongate, third to seventh Fig. 1.

The prothorax is two-tenths of a of the rostrum. millimeter longer than broad. sides arcuate from apex and base to the middle, constriction slight at the apex, disk with small regular tubercles and punc tures similar to the ones on the elytra, and with small median line; squamae The elytra are a third longer are larger and whitish on the sides and coxae. than wide and a third wider than the thorax; the humeral angles not promi nent, sides evenly arcuate posteriorly, nine rows of striae on each elytron, with deep, close-set punctures which are clearly seen on dissected specimens. The intervals are flattened and covered with round squamae and hairs from the tubercles and punctures. The elytra cover the abdomen and are slightly are longer. The ventral portion The body length to of the body is covered with whitish squamae and hairs. the anterior border of the prothorax is 8.2 mrn, breadth 3.8 mm. prominent at the declivity, where the setae Contribution No. 71 from the Entomological Laboratories, Brigham Young Univer sity, Provo, Utah. 147 |
