240 GEO. H. HORN, M. D. 



This sjiecies has much the form and size of comans, but differs in 

 important structural characters. A careful study shows that it 

 must be associated with crassissima, although of very much less 

 robust facies. 



Taken near Jacksonville, Florida, by the late Edward Tatnall. 



26. Li. errans Lee. — Oval, slightly oblong, moderately robust, nifocastane- 

 ous to brown, shining. Clypeus very nearly entire, concave, the border rather 

 widely reflexed, the surface coarsely and moderately closely punctate, front more 

 coarsely and densely. Thorax arcuately narrowed from base to apex, the mar- 

 gin serrate and fimbriate with long hairs, the punctuation coarse and deep, very 

 regularly placed and moderately close, a feeble basal channel. Elytral punctua- 

 tion less coarse than the thorax and closer, rugulose, especially along the suture, 

 sutural costa narrow, the discal costse very faint or wanting, submarginal very 

 faint, border of elytra with long fimbriae. Pygidium moderately coarsely, but 

 not closely punctate. Metasternum densely punctured, the hairs long and dense 

 in both sexes. Abdomen sparsely punctate, the last two segments more coarsely. 

 Claws curved, the tooth median, small "J, , strong ?. Last joint of maxillary 

 palpi fusiform, not impressed. Length .60 — .75 inch ; 15 — 19 mm. 



Male. — Antennal club equal to or longer than the stem. Abdo- 

 men flattened at middle, penultimate segment (fig. 32) with a strongly 

 elevated arcuate carina arching anterior to the middle of the seg- 

 ment. Last segment flat. Inner spur of hind tibiae slender and 

 acute, two-thirds as long as the outer, which is slender. 



Female. — Antennal club shorter than the funiculus. Last seg- 

 ment with an impression along the apical border, which is broadly 

 emarginat^. Legs, especially the posterior, stouter than in the male, 

 the hind tarsi shorter. 



Variations. — The color of this species varies but little. The 

 sculpture may be comparatively smooth or quite rugulose. This 

 seems to depend on locality, those from the south of California are 

 smoother than those from the north or from Oregon, while the 

 Nevada specimens are quite rugulose. 



The antenna show a decided tendency to vary in the number of 

 the joints. While the majority of the males are lO-jointed, a speci- 

 men in my cabinet has nine joints on one side. Four females are 

 before me, all of which have 9-jointed antennae produced by the 

 coalescence of the third and fourth joints without trace of suture. 



The club of the male antennae varies in length, sometimes barely 

 as long as the stem, in others very distinctly longer. In these latter, 

 as if by compensation, the arcuate ridge of the penultimate ventral 

 is less strongly elevated.
