of the elytra are not rounded, the siitural angle quite distinct, and 

 the pygidium covered. 



Occurs in Mendocino County, California. 



19. L<. insoleiis n. sp.— Oblong oval, pale rufotestaceous, moderately convex 

 and shining. Autennfe longer than half the body, pale rufotestaceous, joints 

 2-3-4 equal in length. Head smooth, a few coarse punctures near each eye. 

 Thorax one-third wider than long, not narrowed in front, sides obliquely trun- 

 cate in front, then feebly arcuate, base arcuate, without marginal line; disc 

 moderately convex, sparsely, finely and indistinctly punctate. Elytra not wider 

 at base than the thorax, oval, humeri and umhone indistinct, sutural angle ob- 

 tuse, disc moderately coarsely, not closely punctate, punctures very little finer 

 to apex. Body beneath and legs colored as above. Abdomen coarsely punctate. 

 Length .08 inch. ; 2 mm. 



This species is considerably larger than either of those with which 

 it is associated. It resembles some of the paler forms of melanurus, 

 and also alternatus, but is readily known by the rounded humeri and 

 absent um bones. 



Occurs in Virginia and New Jersey. 



20. It. perforatus n. sp. — Elongate oval, very convex, rufotestaceous, 

 shining. Antennse with four basal joints pale, the outer brown. Head smooth, 

 shining. Thorax one-third wider than long, not narrowed in front, sides straight, 

 anterior angles obliquely truncate, base broadly arcuate, disc convex, slightly 

 alutaceous, the punctuatioti rather coarse, but indistinct and sparse. Elytra not 

 wider at base than the thorax, form regularly oval, umbones not evident, sutural 

 angle well defined, p.vgidium entirely concealed, disc convex, the punctuation 

 relatively ver,v coarse, deep and rather close, well marked at sides and apex. 

 Body beneath concolorous. Abdomen indistinctly punctate. Legs pale yellow- 

 ish. Length .05 inch.; 1.25 mm. 



This minute species may be known in the apterous series by its 

 color and the coarse elytral punctuation. The elytra meet fairly at 

 apex and conceal the pygidium completely. 



Occurs at Tampa, Florida (Schwarz). 



21. li. solidagiiiis n. sp. — Oblong oval, convex, piceous black, without 

 metallic lustre. Antennse longer than half the bod.v, rufotestaceous, slightly 

 darker at tip, joints 2-3-4 equal in length. Head smooth, impunctate. Thorax 

 one-fourth wider than long, not narrowed in front, base moderatel.v arcuate, 

 hind angles distinct, but obtuse, sides nearly straight, anterior angles obliquely 

 truncate, with slight po.st-apical angulation, disc convex, without basal marginal 

 line, surface not very shining, pun(;tuation moderate, not closely, but very regu- 

 larly placed. Elytra not wider at base than the thorax, humeri oblique, umbonc 

 wanting, form regularly oval, gradually narrowed at apical third, the apices 

 separately rounded, leaving the tip of the pygidium exposed, disc convex, mod- 

 erately, coarsel.y, deeply and closely punctate, not smoother at apex. Body be- 

 neath piceous. Abdomen indistinctly punctate. Legs rufotestaceous, the poste- 

 rior femora brown. Length .04— .05 inch.; 1 — 1.25 mm.
