1. Limneria albispina. (Tab. XI. fig. 13.) 



Nigra ; pedibus runs, mandibulis, palpis, trochanteribus anterioribus, tibiis posticis tarsorumque basi, albis ; 



tarsis posticis (basi excepta) tibiarumque apiee nigris ; alis hyalinis, stigmate nigro. $ . 

 Long. 9 millim. ; terebra 3 millim. 



Bab. Mexico, Ciudad in Durango 8100 feet (Forrer). 



Antennee moderately stout, microscopically pilose, as long as the abdomen. Head 

 and mesonotum semiopaque, finely punctured ; the middle of the mesopleurae shining 

 and impunctate ; the rest longitudinally striated ; metathorax finely and closely punc- 

 tured, covered with longish silvery-white hair; the punctures in the middle of the 

 metanotum almost forming striations. Petiole longish, narrow at the base, the apex 

 clavate, shining, aciculate ; the other abdominal segments coarsely aciculate at the base, 

 pilose at the apex and sides. Abdomen somewhat laterally compressed on the lower side 

 at the apex. Hind tibiae with a narrow black ring towards the base; tibial spurs 

 longish and white ; nearly the basal half of the metatarsus and the extreme base of the 

 other segments also white. 



2. Limneria alpestris. 



Nigra; pedibus rufis, basi coxarum anterioribus tarsisque posticis nigris, basi tarsorum posticorum alboj 



alis fere fuscis, nervis nigris. $ . 

 Long. 8 millim. ; terebra fere 2 millim. 



Bab. Mexico, Ciudad in Durango 8100 feet (Forrer). 



Head closely pilose ; metapleura sparsely clothed with longish white hairs ; meta- 

 thorax not so strongly punctured as in L. albispina, and, as in that species, there are no 

 clearly defined area?, only a transverse keel round the top and one down each side. 

 Areolet subpetiolate above, triangular, slightly angled beneath where the recurrent 

 nervure is received near the apex. Similar in form and clothing to L. albispina, but 

 with the body more slenderly built ; the abdomen longer and narrower compared to the 

 thorax, and not punctured, only faintly aciculate; the petiole longer and narrower, 

 narrow at the base, clavate at the apex, and longer than the second segment; the 

 ovipositor shorter, being not much longer than the three apical segments ; there is 

 no white on the hind femora; and the wings are fuscous tinted, the stigma livid 

 testaceous. 



3. Limneria sonorensis. (Tab. XIII. fig. 6.) 

 Eab. Mexico, Northern Sonora (Morrison). 



Similar in coloration to L. albispina, except that the abdomen is broadly reddish-
