with the general color very dilute in the normally covered section of the dextral

 tum, 2.8; length of tegmen, 8.1; greatest width of tegmen, 2.7.

Porto Velho, Rio ]\Iadeira. (Mann and Baker.) One 

 female. 



The diagnostic features given by Burmeister in his very brief 

 description are fully evident in this material, of which the Porto 

 Velho specimen shows the following measurements: length of 

 body, 18 mm.; length of pronotum, 3.1; greatest width of prono- 

 tum, 2.6; length of tegmen, 21; length of cephalic femur, 4.5. 

 The Para specimen differs from the Porto Velho one in having the 

 fuscous cloudings of the head and pronotum much reduced, while 

 the pattern on the limbs is as complete and intense as in the 

 Porto Velho representative. The cerci of the Para specimen are 

 complete except possibly the last joint, and in length are little 

 more than one-half as long as the abdomen. 



The present records considerably extend the range of the 

 species to the westward.

This specimen fully agrees with the description of the species, 

 but is distinct]}^ smaller, as would be expected, the species having 

 been described from the female sex. The dimensions of the male 

 are as follows: length of body, 12.7 nun.; length of pronotum, 2.1:
