CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 63 



though irregular. The pronotal punctures of a single specimen from 

 Georgia are much denser than usual and show a tendency toward 

 becoming longitudinally elongate; this is similar to but not nearly as 

 pronounced as the condition of the sculpture in schreibersii. In the 

 Georgia specimen, the elytral punctures of the disk tend to form 

 double rows. This tendency is less pronounced or absent on the other 

 seven specimens on hand. 



Collection data provide the records, skeletonizing leaves of Quercus 

 virginiana Mill, and Prunus angustifolia Marsh. 



Distribution. — The eight specimens in the USNM collection are 

 from Florida, Georgia, and North CaroUna.

 Cryptocephalus leucomelas SufiFrian, 1852, p. 36. 



Pronotum: Creamy yellow to orange, -with four red to brown or 

 black, longitudinal, sharply delimited vittae from base to apex, some- 

 times narrowly meeting at apex or base. Punctation dual, smaller 

 punctures sometimes sparse, larger punctures small to moderate in 

 size, sometimes coarse. Profile more declivous than usual. 



Elytra : Creamy yellow to orange with red to brown or black markings. 

 Each elytron with dark markings as follows: a transverse band at 

 basal third, broadly meeting suture before apex of scutellar stria, 

 often expanded to humerus and nearly to base; a transverse band just 

 behind middle from about fifth stria to suture; humeral and sub- 

 humeral spots (latter may join basal transverse marking); a lateral 

 spot at about apical thu-d; two apical spots; markings sometimes 

 reduced or sometimes expanded and forming three nearly or quite 

 complete transverse bands. Punctures larger, sparser, more distinctly 

 impressed than usual, finer as usual apically; with eight rows of 

 punctures, fifth row sometimes confused, sixth row much reduced, 

 confused, seventh row confused, often reduced ; inner and outer rows 

 distinct at apex, nearly always clearly meeting, infrequently some- 

 what confused. 



Prosternum: Male with anterior margin produced into a ventrally 

 directed, rather pointed lobe to just somewhat produced; female uith 

 anterior margin feebly produced to evenly arcuate. 



Length: 4.0 to 6.0 mm. 



Discussion. — A single specimen from the Monros collection deter- 

 mined as C. guatemalensis Jacoby (collected at Presidio, Mexdco) is 

 very similar to I. leucomelas. It difi'ers in that the punctures on the 

 yeUowish areas of the elytra are confused and show little or no tendency 

 to align in rows (those on the transverse dark markings are clearly
