sexes of one species canclla. There is no good reason why it 

 should not be so. The following are the descriptions of the 

 new species. 



Plenocolus foxii, n sp.* 



Clypeus produced, like a blunt beak, dorsulum closely punctured espe- 

 cially medially, enclosure of metanotum longitudinally striate, pygidium 

 almost impunctate. 



9. Length 5 mm. Clypeus longitudinally raised medially with a tri- 

 angular smooth to polished area, from the apex of which there extends 

 back on the front, terminating before its middle a longitudinal sort of 

 carina. Front convex, very finely punctate or rugulose. Space between 

 posterior ocelli distinctly greater than that between them and nearest eye 

 margin, cheeks indistinctly sculptured, dullish, finely silvery sericeous, the 

 raised portion of the front (which extends down to a point meeting the 

 supraclypeal carina) indistinctly sericeous, almost bare, the depression 

 on each side of the raised space satiny, the clypeus less so. First flagel- 

 lar joint longer than the second, but not as long as the second and third 

 joints united. Pronotum very finely sculptured. Dorsulum slightly im- 

 pressed medially where it is closely finely punctured, there is a slight 

 indication of a line to each side of this median impression, beyond which 

 the dorsulum is provided with separated and more distinct punctures and 

 also a faint impression. Mesapleurae with a longitudinal impressed line, 

 the sculpture obscured by a silvery appressed very short pubescence. 

 Scutellum uniformly finely sculptured. Disc of metathorax finely rugu- 

 lose, with separated imperfectly formed longitudinal striae. The sides of 

 the metathorax finely indistinctly striate, silvery sericeous. Dorsally the 

 thorax is no more pubescent than the front. Second recurrent nervure 

 received by the second submarginal cell a little beyond the middle. Ab- 

 domen subopaque, finely indistinctly sculptured, the segments with a 

 transverse apical impression, partly sericeous, more conspicuous and 

 silvery on the sides. Pygidial area shining. 



Black ; mandibles whitish on basal half, ferruginous to brown on apical 

 half A line on pronotum with a broad interruption medially, the tubercles 

 and tegulae partly, postscutellum, the four anterior femora apirally and all 

 the tibiae above primrose yellow, the tibia? beneath and the tarsi entirely, 

 brown or brownish. 



.Length 4 mm. Differs from the female in having tin- rlypeus pi- 

 duced into a truncate production with a median tooth, and in tin- indis- 

 tinctly finely sculptured sides of the metathorax. hi color it (lifters by 

 the markings being more lemon yellow, the tarsi in part unicolorous with 

 the markings. The tibia; pale brown beneath, and the flag. -Hum \\itli a 

 brown space taking in about all of joints three, four and live.
