count of the nature of the paper) presented in detail the evidence in 

 support of his theses and the reviewer is accordingly unable to give 

 an analysis of the evidence upon which they rest. There is, however, 

 much evidence that the Cicindelidae originated in Africa, but their 

 origin from wingless forms with elytra, I fear, will not meet the ap- 

 proval of insect morphologists. On the other hand, it is evident that 

 Tetracha is in many of its characters a more primitive form than 

 Cicindela and its distribution speaks well for the author's conclusions. 

 His analysis of the nearctic Cicindela fauna and statement of its affini- 

 ties must, it seems to me, stand unchallenged, while his arrangement 

 of our species is the most tenable yet presented.

ON THE KNOWN LARVAE OF' THE GENUS 



URANOT/EN1A. , 



By Evelyn G. Mitchell, 

 Washington, D. C. 



The receipt during the past summer of larva? of Uranotcsnia sap- 

 phirina and U. loivii from Dr. T. W. Dupree gave an opportunity for 

 a critical comparison of the three known larvae of this genus, which 

 had not previously been distinguished from each other. The genus, 

 so far as can be judged by the known larvae, is characterized as follows : 



Four large stout spines bearing spi miles instead of the usual four 

 tufts in the middle of head ; antennae with a few scattered spines, the 

 tuft represented by a single hair ; stellate hairs on thorax and abdomen. 



Synopsis of Species 



1. Antennal tuft decidedly over one third distad ; longest terminal spine if bent back- 

 ward would reach below tuft. Scales on eighth segment of abdomen not fringed 

 on apical one-third (reckoned from center of base to tip). Central tooth of 

 labial plate bluntly rounded and widely separated from adjacent teeth. 



U. lowii.
