THE CANADIAN ENTOMOLOGIST. 



In the following table the length of the segments of the. legs and the 

 palpus is given in nnillimeters. Owing to the difficulty of determining the 

 division between the tarsi and the metatarsi because of the presence of 

 several false articulations, I have for convenience in the table considered 

 the first segment after the tibia as representing the metatarsus, the 

 remaining segments the tarsus.

Three specimens, Columbia, Mo., November 8 and 20, 1904, July 12, 

 1905, collected under leaves on a heavily wooded north slope on the bank 

 of Hinkson Creek. 



I place this species in Nemastoma for the present, although it differs 

 from it in the separation of the dorsal plate of the cephalothorax from the 

 tergites of the abdomen, the presence of a transverse groove on the 

 cephalothorax back of the eye tubercle, the exposure of the stink glands, 

 the suppression of the anal sternite, and the dentition of the digits of the 

 chelicerse. 



RANDOM NOTES ON ENTOMOLOGICAL FIELD WORK.^ 



BY E. S. TUCKER,

Opportunities often occur in entomological field work for the obser- 

 vation of interesting features of insect life apart from the main subject of 

 investigation. Such features in many cases are presented in connection 

 with the regular observations^ but independently as time permits, casual
