298 SUPPLEMENT. 



posterior angle broadly yellow. Femora black ; their tip, the tip of the tibiae, and the basal joints of 

 the tarsi, yellow ; tibiae and tarsi otherwise reddish or brownish. Wings tinged with yellowish. Length 

 6-7 millim. 



Hab. Mexico, Xucumanatlan and Amula in Guerrero 6000 to 7000 feet (H. II. 



Smith). 



Four specimens. In one of them the yellow on the margin of the fourth and fifth 

 abdominal segments is wanting. Although the markings are very similar to those of 

 P. truquii and P. conica, the present species cannot be identified with the former on 

 account of its black colour, nor with the latter by reason of yet more pronounced 

 differences. 



2. Philopota dolorosa, sp. n. 



Very much like P. lugubris ; but the frontal triangle is larger, reaching midway to the ocelli ; the abdomen 

 is wholly without yellow, save the very narrow lateral margins of the segments ; the mesothorax also 

 lacks the large yellow spots, and there is only a small reddish spot on each side of the posterior margin 

 of the pronotum. The legs are black, with the knees and basal joints of the tarsi reddish. Length 

 6-7 millim. 



Hab. Mexico, Amula in Guerrero (H. H. Smith). 



One specimen. I cannot believe that the strongly marked differences between this 

 and the preceding species are merely varietal, though such is possibly the case. I am 

 unable to determine the sex : it appears to be the same in our examples in both 

 forms.

LEPTOGASTEE, (p. 167). 



Three Mexican species of this genus were briefly noticed by Osten Sacken in the 

 earlier part of this work, but none of them were known to, or identified by, him. The 

 supplementary collections since received contain representatives of eight others, which 

 may be tabulated thus : — 



1. A row of well-developed bristles on the upper part of the occiput ... 2. 

 No upper occipital bristles present 5. 



2. Empodia nearly as long as the ungues ; mesonotum for the most part 



shining black triungulata, sp. n. 



Empodia very much shorter than the ungues 3. 



3. Mesonotum shining reddish-yellow for the most part rubida, Wiedem. 



Mesonotum wholly opaque 4. 



4. Third antennal joint black crocea, sp. n. 



Third antennal joint yellow concinnata, sp. n. 



5. Empodia present 6. 



Empodia wanting 7.
