of which is a conical lobe, short, open at tip. }} r ing-/css female.

 between appendages is a small thin elongated lobe.

 Head cut straight before prothorax ; second joint of antennae 

 very small, annular ; third joint as long as two basals, thicker

Embia texana is very susceptible to differing degrees of humid- 

 ity and therefore cannot be found at all seasons of the year. After 

 the ground has been moistened by the winter rains the Embiids 

 were found, the last one being taken during March. As soon as 

 the overhead sun dries up the ground these insects are never 

 seen, having burrowed deeply into the soil. One specimen was 

 taken while ripping the bark from a fallen tree, all the others 

 were found under stones ; and of these one was found in com- 

 pany with Formica fnsca L. var. gnava Buckley, though its 

 association with the ants was accidental, no doubt, as was shown 

 by its hurry to escape. In this connection attention may be 

 called to the occurrence of the Olyntha in the nest of Leptogenys. 

 Euibia texana is apparently not rare in this vicinity, two having 

 been taken in a single day, though from its neat manner of con- 

 cealment and its limited time of appearance it is found only by 

 the merest chance. The species has been taken in localities 

 about the city of Austin separated by over ten miles, places of 

 different character, one a sandy tract, and the other a limestone 

 hill. 



The insects live singly in silken webs, spun by themselves. 

 These webs are tunnels in some niche of the rock which shelters 

 them, or spun between the grains of soil. They are an inch or 

 more in length, and closed at one end, their diameter a little 

 greater than the insect's body. Sometimes a small flat web is 

 spun beneath the stone. The tunnels are provided with side-
