Genus Glyptina LeConte

Glyptina LeConte, 1859, Col. of Kans., p. 26.
Balophila Crotch, 1873, Proc. Acad. Nat. Sci. Philadelphia 25: 65.
     Minute or small, broadly oval to oblong oval species. Frontal tubercles distinct. Antennae 1/2 body length. Prothorax broader than long, without longitudinal or transverse basal impressions. Elytra punctate-striate. Posterior tibiae with medial apical spur, outer edge grooved near apex. First segment of hind tarsus 1/3 length of tibia, equaling combined remaining segments. Tarsal claws simple.
     Six described species are known from the State. A 7th, possibly new, will be described if further study reveals its uniqueness. This form is presently represented in the Auburn University collection by only a single specimen (from Baldwin County).

G. FERRUGINEA BLATCHLEY*

     Alabama records: 36 specimens from Lee1 County.
     Seasonal distribution: April 9-December 2.

G. MARITIMA FALL*

Glyptina maritima Fall, 1927, Canadian Entomol. 59: 140.
     Elongate oval, subconvex. Pale dull yellow-brown; antennae, legs, and venter concolorous with dorsum. Posterior femora brown. Head smooth, impunctate.

Remarks: This specimen greatly extends the range of this species. Previously it was known only from 6 Massachusetts specimens. Fall (55), in his description of this species, noted that "maritima is probably restricted to the vicinity of the shore line."
