H. C. FALL 419 



about four-fifths as long as the bodj^ in the male, the tenth joint fully four 

 times as long as wide, basal joint entirely blackish, outer joints infuscate. 



Prolhorax only moderately transverse, sides broadly arcuately convergent 

 from the base or very near it, punctuation dense, sides not smoother; surface 

 predominantly fuscous, mottled with dull yellow, the usual two basal and 

 anterior median spots most conspicuous. 



Elytra only about one-eighth longer than wide, dull yellow with l)lackish 

 brown punctures for the most part, confusedly tlisjwsed on the disk but tend- 

 ing to form irregular or sinuous lines toward the sides and apex, the two outer 

 striae fairly continuous and entire; strial lines feebly impressed, marginal 

 interspace punctate, shield small but convex and distinct ; marginal series of 

 standard spots feebly indicated, discal ones scarcely so, l)ut witli a tendency 

 to some fuscous suffusion along the suture. 



Pygidimn black with two oval yellow spots and between these and the side 

 margin and contiguous to the latter a small yellow tlot. Body beneath black- 

 ish, last ventral with a lateral yellow spot. Front thighs yellow with base 

 and upper surface blackish, front tibiae largely yellow; middle thighs yellow 

 in outer half, the tibiae pale in basal half. 



Length 2.9 to 3.25 mm.; width 1.6 to 1.8 mm. 



Distribution. — Alabama: Mobile, June (Loding), tyi)e o". Georgia: (Lie- 

 beck Coll.). Mississippi: Agricultural College, July (Weed). Louisiana: 

 Opelousas (Wenzel); Cameron, Aug. 19 (Dury). 



The specimens aggregated under the name cephalicus are seen 

 on closer inspection to involve several more or less distinct types, 

 two of which, for the piu'poses of a more discriminating cabinet 

 arrangement, may with advantage be given varietal names. It 

 is possible that one or lioth of these may be distinct from the 

 larger typical form, but until a more extensive material shall have 

 become available for study I prefer to give them only varietal 

 standing. 



\'ar. dixianus new varietj^ 



Smaller than the typical form — 2.5 to 2.8 mm. — the e\-es slightly less prom- 

 inent, the elytral maculation relatively a little coarser, the pale yellow and 

 blackish spots prettily contrasting, the shield relatively larger, the marginal 

 interspace more sparsely punctate or even subimpunctate in posterior half. 



Distribution. — The types (cf and 9) were taken at Tumbling Ciap in 

 Northern Alabama by Mr. Loding. A si)ecimen from Meridian, Miss. (8ol- 

 tau in Nat. Mus. Coll.), and another from "Barlow" (Miss.?) are closely 

 similar. 



V'ar. parvus new variety 



Still smaller than dixianus — 2.2 to 2.6 mm. — Eyes — as in dixianus — a 

 trifle k'ss prominent than in typical cephalicus, the elytral shield smaller rela- 

 tively than in typical cephalicus, and \ery distinctly smaller than in di.rianus; 

 cjuite similar to the typical form in the broadly confused punctuation, the
