not having the silvery patches, the second abdominal segment without the maculae, and 

 the following segments clothed with deep golden pubescence. 



The following six species have the form and coloration of M. tolteca, but they are 

 smaller (from 3-7 millim.) ; the body is dull ferruginous ; the antennae and legs are 

 reddish ; the thorax and abdomen sometimes have black markings ; the head with 

 golden or brassy pubescence ; and the abdomen at the apex mostly fiery-red or golden. 

 The annexed table will aid in their identification : — 



1 (2) . The apex of the median segment in the middle armed with a broad projec- 



tion, which ends in a tooth bugabensis. 



2 (1). The apex of the median segment without a tooth or projection. 



3 (8). The second abdominal segment more or less black, and without white 



maculae. 



4 (5). The black mark on the second segment large, triangular in shape; the 



thorax without black triangularis. 



5 (4). The black mark on the second segment not triangular; the thorax marked 



with black down the sides. 



6 (7) . The apical segments of the abdomen densely covered with golden pubescence ; 



the third antennal joint distinctly longer than the fourth pantaleonce. 



7 (6) . The apical segments of the abdomen without golden pubescence ; the third 



antennal joint not longer than the fourth approwimata. 



8 (3). The second abdominal segment without black, and marked with two white 



maculae. 



9 (10). The middle of the second abdominal segment, and third entirely, punctured 



and densely haired chiriquensis.

Ferruginous ; the head golden ; a mark on either side of the rnesonotum, a bifurcated 

 large mark on the median segment, and some marks down the sides of the abdomen, 

 black ; the apex of the first abdominal segment, two lines down the base of the second 

 segment, and two large marks on the apex of the latter, silvery-white ; the other 

 segments golden. Head with long fuscous hair, wider than the thorax, not much 

 narrowed behind the eyes, which are large ; the mandibles blackish at the tips. The 

 scape of the antennae covered with white hairs ; the flagellum with a white microscopic 

 pile. The thorax about twice the length of the head, straight to the median segment, 

 where it becomes narrowed, coarsely punctured, sparsely covered with long fuscous hair ;
