76 U.S. NATIONAL MUSEUM BULLETEST 290 



Type data. — All four specimens were taken at Wrentham, Massa- 

 chusetts, on July 9, 1947, by B. E. White. The male holotype, the 

 allotype, and a male paratype are in the CAS collection. A single male 

 paratype is in the U.S. National Museum. 



Discussion. — This subspecies is distinguishable from o. obsoletus 

 by the development of the prosternal spine and on the basis of color. 

 In 0. obsoletus, the female bears a short, broad spine; the male has a 

 broad, pointed spine. In o. indistinctus, both sexes bear an elongate, 

 pointed spine distinctly longer than in either sex of o. obsoletus. Also, 

 0. obsoletus bears two vague to distinct, longitudinal dark stripes; in o. 

 indistinctus, these are vague to obsolete. In addition, o. obsoletus is 

 known only from Vu'ginia to Florida and Louisiana, and o. indistinctus 

 is known only from Massachusetts; finally, o. obsoletus ranges in length 

 from 4.3 to 6.0 mm. and o. indistinctus is 3.9 to 4.3 mm. long. The male 

 genitalia of o. indistinctus are essentially the same as the illustrations 

 for those of o. obsoletus. 



Cryptocephalus ochraceus Fall 



FiGURK 36 



Cryptocephalus ochraceus Fall, 1932, p. 25. 



Pronotum: Dull creamy yellow with large punctures red, disk ii'- 

 regularly clouded with red; punctation dual, larger punctures large, 

 coarse. 



Elytra: Dull creamy yellow but with striae, humerus, and irregular 

 lateral spots reddish. With nine more or less regular rows of punctures, 

 these of ten with a puncture or two misplaced, often confused apically, 

 rows six, seven, and eight confused; punctures as large and dense but 

 more distinctly impressed than usual, only slightly finer apically; 

 inner and outer rows at apex obscured by confused punctures, not 

 meeting. 



Prosternum: Anterior margin in female evenly arcuate; male not 

 examined. 



Length: 5.1 mm. 



Discussion. — The above description is from a single female taken 

 at Capron, Florida. 



Cryptocephalus pallidicinctus Fall 



Cryptocephalus pallidicinctus Fall, 1932, p. 21. 



This is the only described North American species I have not seen 

 during this work. FoUowmg is Fall's original description: 



Moderately robust. Head black, a quadrate post-clypeal area, a small spot 

 posteriorly adjacent thereto, and the entire inner border of the eyes narrowly 

 whitish yellow. Antennae black.
