tropicus. Several differences are also quite evident between the larvae 

 from the^jtwo localities. Not enough larvae have been found to 

 establish any limits of variation and it is possible that the larvae are 

 generally as variable as the adult. 



The Southern Pines larvae of subtropicus differ from the larvae of 

 lazarus described by Kitcher in the following respects: Maximum 

 width of head capsule 2.0 mm., frons on each side with two or three 

 posterior frontal setae. Otherwise, head capsule and antenna (pi. 6, 

 fig. 1) appear similar. 



Mandibles similar to the Arkansas specimens but with the anterior 

 portion of the scissorial area produced into a tooth, which may have 

 been worn away in the Arkansas specimens. Maxillary stridulating 

 area with a patch of 12 to 18 small, sharp, conical teeth on each side. 

 Hypopharynx with two slightly asymmetrical oncyli covered with 

 fine setae. Glossa with small setae extending enth-ely across anterior 

 portion (pi. 6, fig. 6) . These setae appear to be lacking in the Aikansas 

 specimens (Ritcher, 1947, p. 25, fig. 30). Haptolachus with appar- 

 ently two sensilla on each side, mesally with a dense, well defined 

 phoba (pi. 6, fig. 6), which differs somewhat in outline from the 

 Arkansas specimens. 



Body (pi. 12, fig. 2) not humped or conspicuously swollen. Seg- 

 ments as described by Ritcher. Anal opening (pi. 6, fig. 7) more 

 Y-shaped than V-shaped. Otherwise structures appear similar. 



The most noticeable difference between these larvae and other ones 

 described by Ritcher are in the shape of the glossa and in the fact that 

 the setae extend completely across anterior portion of the glossa in 

 subtropicus. 



Eucanthus alutaceus Cartwright 



Eucanthvs lazarus var. alutaceus Cartwright, 1944, p. 30. Type, male, Missis- 

 sippi (USNM). 



Length 11 to 14 mm., greatest width 6.5 to 7.5 mm. 



Color of dorsum oily dark red-brown; head, thorax, and sutural 

 intervals slightly darker than elytra. The oily appearance is due to 

 the fine alutaceus appearance of the dorsum. Color of antennal club 

 reddish brown. Ventral portions of thorax and abdomen the same or 

 slightly darker in color than dorsally. Tibia darker brown to black. 

 Punctiu-es of vertex very few and sparse in both sexes. Coarse punc- 

 tures of clypeus, eye canthi, and pronotum identical to those of E. 

 lazarus lazarus. Secondary punctures of pronotum very fine, much 

 less noticeable than in most specimens of lazarus lazarus. Punctures 

 of elytral striae moderate, separated by a distance usually slightly 

 more than their diameter. Elytral punctures without setae except 

 those on the margins of the elytra and epipleura, where a few of the 

 punctures bear long reddish setae. Width of elytral striae similar to
