GALERUCINE BEETLES — BLAKE 85 



the anterior side of the pronotum being small and near the anterior 

 margin. This spot, located on each side of the pronotum, is half 

 hidden when viewed from above and is usually much smaller than in 

 the other closely related species. The antennae tend to have pale 

 brown tips. This is one of the two species figured by Jacoby (1892) 

 under Diabrotica sexplagiata, the drawing having been made from a 

 specimen from Belize, British Honduras, having no pronotal spots. 



Iceloceras parviplagiatum teapense, new subspecies 



Figure 2,d 



About 4,5 mm. in length, elongate oblong oval, somewhat alu- 

 taceous, faintly shining, head and pronotum almost impunctate, 

 elytra with dense coarse punctures; pale yello%\ , the pronotum with a 

 black spot (usually small) on anterior lateral half on each side, the 

 spot never extending as much as half-way down, in one specimen 

 entirely lacking; elytra dark with three pale yellow spots and a pale 

 margin on each, the pale spots sometimes confluent; antennae entirely 

 dark, middle and posterior tibiae and tarsi dark, and femora dark 

 at apex. 



Head wth interocular space half its width; smooth, impunctate, 

 frontal tubercles distinct, a very short elevated hne between antennal 

 sockets not extending down front. Antennae usually entirely dark, 

 but in two specimens the last two or three joints paler, 3d joint shorter 

 than 4th. Prothorax wider than long with slightly curved sides and 

 semicircular transverse depression across disk; alutaceous, very finely 

 punctate; pale with a dark piceous spot on each side, in anterior half 

 barely reaching half-way dowTi, and usually small, in one specimen 

 entirely lacking. Scutellum pale. Elytra densely and coarsely 

 punctate with faint sign of longitudinal ridging; piceous with three 

 large pale spots, often confluent, on each elytron, the margin pale. 

 Epipleura disappearing at apical curve; last two ventral segments 

 entirely dark on upper side; femora pale with dark apex; tibiae of 

 anterior legs dark on one side, middle and posterior tibiae and tarsi 

 entirely dark. Length 4.3 mm.; width 1.8 mm. 



Type: Male, in Museum of Comparative Zoology (No. 29611), and 

 six paratypes, from Teapa, Tabasco, Mexico, H. H. Smith, in 2d 

 Jacoby collection, Bowditch collection. Also one specimen taken at 

 Teapa by Salle, 1st Jacoby collection. 



Remarks: This subspecies is smaller and darker than the more 

 southern race, having entirely dark antennae and usually larger side 

 spots on the pronotum, although they are sometimes lacking. In 

 both races is found the tendency for the elytral pale spots to be 

 confluent.
