of the dorsum of the pronotum more strongly raised and arcuate 

 than in the adults. 



The immature examples before us range in size from a very early 

 stage of development to the instar preceding maturity. These 

 specimens are very singularly colored, being blackish overlaid with 

 mars orange, the latter color forming a pale stripe on the post-ocular 

 portion of the head and strongly indicated over the face and the 

 constricted distal portion of the caudal femora. One of these 

 specimens, which has apparently best retained its coloration, has 

 the face nopal red. In life these specimens have a striking metallic, 

 velvety lustre, which in the dried examples is still weakly indicated. 



A very slight increase in size southward in individuals of the 

 species is shown by the present series. Females from Fayetteville 

 are among the smallest before us (length 15.5 to 16. mm.), while the 

 specimen of that sex from Live Oak is the largest (length 20. mm.). 

 In the series from Spring Creek the female is rather large, but the 

 males are as small as any in the present series (length 10. to 11. mm.). 

 The majority of specimens of this species have the abdomen decidedly 

 upcurved, which makes the measurement for the insects shorter 

 than would otherwise be the case. 



We have noticed that this species is rather sluggish in its actions 

 and was found to cling tenaciously to the stems of wire-grass, for 

 which plant it showed a decided preference. The species was found 

 in this wire-grass in short-leaf pine and oak woods (Fayetteville, 

 Florence, Yemassee, Warm Springs), and in the same plant in moist 

 but not swampy places in long-leaf pine woods (Albany, Hebardville, 

 Homerville, Live' Oak), at the latter locality being found also in 

 wire-grass and oak sprouts on the sides of a sink which apparently had 

 been recently deforested. The six specimens taken at Fayetteville, 

 after long and diligent search in a restricted area', constitute the 

 only series from a single localrty we have yet been able to secure 

 of this rare insect, which was previously known only from Denmark, 

 South Carolina, and Waycross and Thomasville, Georgia. It is in- 

 teresting to note that its range is not confined to the coastal plain 

 and that it has not been found within the range of E. signatus.
