given her opinion that it is probably correct. In examining the specimens from 



Mt. \\ elhngton referred to /). mficonus Macq., bv Miss Ricardo, I was struck 



with the difference in the ,,alpi between these sj.ecimens and others identified as 



D. constans W alk. In D. constans the palpi are broad at the base and end in a
