TRIBE XII. ANTHONOMINI. 299 



squaw huckleberry, Vaccinium stanuncinit L., May to June. Re- 

 sembles a small Apion. Easily known by its small size, shining 

 black color, coarsely punctured thorax and sparse pubescence. 



433 (10,991). ANTIIONOMUS SUBGUTTATUS Dietz, 1891, 213. 



Elongate-oval. Dark brown to piceous, shining; legs and base of 

 antennae usually paler; thorax with a narrow median stripe, wider at base, 

 of condensed white pubescence; elytra with two oblique postmedian inter- 

 rupted lines of condensed pubescence reaching from the sides to the second 

 interval, where they unite, the space enclosed between these lines not de- 

 nuded. Closely allied to flavicornis from which it differs as follows: 

 Pubescence coarse, rather dense and white; beak more slender and shining, 

 finely, less closely punctured, its median carina more distinct, extending to 

 frontal fovea; second joint of funicle nearly one-half longer than third; 

 thorax less rounded on the sides, which are almost straight behind, apex 

 not constricted, punctures smaller and remote on the disc, crowded on the 

 sides; tooth of claw very small, arising from side of claw near base. 

 Length 2 2.7 mm. 



Lake Ashley and Jacksonville, Florida. District of Columbia, 

 West Virginia and New Jersey in July. Specimens in the Cam- 

 bridge collection from Lake Ashley and Texas were labelled 

 siibc/Httutiis by LeContc. who named (1870, 190) but did not do- 

 scribe it. 



GROUP D. 



Species not more than 3 mm. in length, having the first and 

 second ventrals slightly longer than in Group C, nearly equal in 

 length, the others gradually decreasing in size, beginning with 

 the third instead of second segment as there (Fig. 79, c) ; elytra 

 with a bare or denuded patch or band behind the middle, sur- 

 rounded in fresh specimens by spots or lines of pubescence; first 

 two tarsal joints equal or nearly so. All the known species, 12 

 in number, occur in our territory. 



KEY TO SPECIES OF GROUP D.

 ft. Front foveate. 

 c. Color uniform reddish-brown. 



d. Larger, 2.3 mm., and more robust; second joint of funicle dis- 

 tinctly longer than third; thorax strongly rounded on sides.

 spicuous.

 latter interrupted on third interval. 434. SIONATUS. 



if. Elytra pitchy black, unicolorous; fascia not interrupted.
