110 AMERICAN HYMENOPTERA. 



to 18 mm. ; male, 12 mm. to 15 mm. Spread of wings: queen, 41 

 mm. to 43 mm. ; worker, 33 mm. to 37 mm. ; male, 30 mm. to 31 mm. 

 Width of abdomen at second segment: queen, 9 mm. to 9.^ mm. ; 

 worker, 6| mm. to 1\ mm. ; male, S^r mm. to 6| mm. 



Queen and worker redescribed from two specimens of each 

 caste. 



Habitat. — I have the following records for this species : 

 Mexico (Orizaba) and Guatemala (Olas de Moka — Dep't 

 Solola — 3,000 feet altitude — two queens). 



This species, in my opinion, has its closest ally in opifex. 

 It was probably on misdetermined specimens of this species 

 that Smith (Cat. Brit. Hym. Brit. Mus., 1876) based his 

 record of lapidarius from *' Mexico."

Types. — St. Fargeau's specimens are probably still extant 

 in the collection of the National Museum of France at Paris 

 and, if they can be positively identified, it can probably be 

 determined whether the name violaceous should be given to
