less alutaceous, and ^vith moderately coarse punctures. Scutellum 

 pale. Elytra faintly alutaceous and densely and coarsely punctate, 

 with irregular ridges giving it a semicostate appearance; piceous with 

 three large pale yellow spots on each elytron, margin pale. Epipleura 

 vanishing at apical curve; last two abdominal segments pale above. 

 Body beneath and legs pale. Length 5.2-6.5 mm. ; mdth 2.4-3.2 mm. 



Type: Male and three paratypes (2 females, 1 male), USNM 

 63356 from Colima, Panama, collected by August Busck. 



Other localities: Panama: Pedro Miguel, A. H. Jennings; Barro 

 Colorado, Canal Zone, May 1929, P. J. Darhngton; Ft. Davis, Canal 

 Zone, Nathan Banks, July 5, 1924. Colombia: Rio Frio, Magdalena 

 Province, P. J. Darhngton. 



Remarks: Of tlie Central American species having pale legs and 

 antennae, this one is the largest of the sexplagiatum group, and is 

 characterized by having longer spots on the side of the pronotum 

 extending nearly to the base. In addition, the pronotum is dis- 

 tinctly punctate. It approaches in size the South American species, 

 /. maximum, but the coloring is different, and the mark on the pro- 

 notum is longer. In the Bowditch collection at the Museum of 

 Comparative Zoology is a specimen from the fii-st Jacoby collection 

 with the label Peru and a name label "Z>. hivittaticollis Baly" (in 

 Jacoby 's handwriting?). The specimen is similar to the above speci- 

 mens from Panama in its markings. It is a male but the abdomen is 

 shrivelled and the specimen so old that I have not ventured to dissect 

 it. Possibly this is the specimen from which in part Jacoby originally 

 drew up his first description of Diabrotica sexplagiata, since the locahty 

 is Peru, Until further specimens from Peru can be obtained, I believe 

 this specimen should be considered the same as Iceloceras flairipes.

 4th. Prothorax about one-third wider than long with slightly curved 

 sides, a semicircular depression across disk, nearly impunctate, shining,
