10 INSECUTOR INSCITI^ MENSTRUUS 



distance from where these specimens were taken, I can not, 

 nevertheless, from the data available, consider them other 

 than this form. 



There are also four 9 specimens in the collection which 

 are referred here with some doubt. Three were taken by 

 Iconnicoff, November 7 and 18 and December 10, 1906, and 

 one by Schunke, November, 1908. They vary in color from 

 dark brown to greenish and the abdominal segments are 

 multicarinate above. The cerci are short and stout, project- 

 ing but little beyond the end of the abdomen. The oper- 

 culum fails to reach the end of the body and is apically entire 

 with a small median triangular tooth. The second segment 

 of the abdomen is distinctly longer than broad but scarcely 

 twice as long. Measurements of the most perfect specimen 

 are: Length, total, 43 mm.; mesonotum, 11 mm.; fore 

 femora, 13 mm. 



Dyme iconnicoffi, new species. (PI. I, fig. 3.) 



This apparently undescribed form seems to be the most 

 nearly allied to Dyme ingenua Brunner from Brazil but is 

 smaller and the posterior femora attains to the tip of the 

 sixth abdominal segment. 



Description ($, the 9 unknown). — General color en- 

 tirely dark brown, the antennae and the fore tibia, especially 

 in apical portion, tending toward reddish or yellowish 

 brown. Entire body, head, thorax, and abdomen somewhat 

 densely covered with small tubercles with a few larger yel- 

 lowish brown blister-like swellings on the mesonotum and 

 metathorax. Head somewhat longer than the greatest width, 

 much broader in front than behind and very little flattened 

 above ; eyes round and prominent ; ocelli not evident except 

 as represented by lighter spots ; antennre long, the first two 

 segments enlarged, the first somewhat flattened as usual. 

 Pronotum dorsally flattened, the disk about twice as long 

 as broad with crossed sulci in the middle ; meso- and meta- 

 notum cylindrical, enlarged at the ends, the former consid- 

 erably longer than the latter; median segment distinct, 

 scarcely longer than broad. Abdomen almost parallel sided
