each lobe and a pair from lateral inarqin midway between 

 second incision and penultimate segment. Ventral groujied 

 glands: median, none; cephalolateral, three to nine; caudo- 

 lateral, one to seven. 



Comstock in the original description gives the number of 

 glands as eight to nine for the cephalolateral and li\e to 

 seven for the caudolateral groups. Specimens in Prof. 

 Cockerell's collection from Frontera, Mex., have three glands 

 in each of the caudolateral and from live to seven in the 

 cephalolateral, whde specimens received from Prof, (lossard. 

 Lake City, Fla , have from one to three in the caudolateral 

 and three to four in the cephalolateral groups It will be 

 seen that the various specimens present a gradation from the 

 lowest numbers given to those given in the original descrip- 

 tion. In all other respects they accord perfectly with Prof. 

 Comstock's figures.
