seen. The subspecies saussurei occurs in Mexico, from which countr}"- 

 1 have also seen an example of the subspecies iheringii^ which is more 

 common in South America. The subspecies guatemalensls^ though 

 first taken in Guatemala, has also been found in Mexico. 



A figure of this in.sect is given in the Insect Book (Plate XI, fig. S.)

This subspecies ditt'ers from the typical form just described by the 

 color of the wings, which ai'e hyaline with a strong yellow tinge and 

 only slightly fuliginous be3'ond the ends of the cells. The pubescence 

 is more al)undant, the l)ody more hairy, there is no short vein entering- 

 the median ceil of the hind wing from the cubital vein in the specimens 

 1 have seen, and the average size seems to be somewhat greater, the 

 females ranging from 2!) to 32 mm., and the males from 20 to 30 mm. 

 in length. 



This subspecies occurs in Mexico, but I have no closer data of local- 

 ities.

 Sphex favipes var. (/natenutletisls Kohl, Ann. natnr. Hdfmus. Wien, V, 1890, p. 



405. 



This subspecies differs from the typical form in the following regards: 

 The abdomen is partly ferruginous, varying in amount; the wings are 

 quite hy;dine, though with the outer margins slightly fuliginous and 

 the inner portion tinged somewhat with yellowish, the\eins dark; the 

 pubescence and hairs, though golden, are rather pale, particularly the 

 latter, and the (juter half of the femui" is ferruginous. The size is 

 about that of average examples of the typical form. 



Though first desciibed from Guatemala, 1 have seen a male which 

 was taken at Tuxpan, Jalisco, Mexico; September 3 (1902?). 



CHLORION (PROTEROSPHEX) FLAVITARSIS IHERINGII (Kohl).

In this subspecies the abdomen is black; the coxi», trochanters and 

 a little of the base of the femora black, also the tips, inner margins, 

 and teeth of the claws; the tips of the hind tibiw and all of the hind 

 tarsi are ])lack, the spines ferrug'inous; the wings are strongly fulig'- 

 iuous, with a pronounced violet to blue reflection; the pubescence
