black below. Wiugs dark fuscous, a lighter cloud beyoud the areolet, extending 

 from the radius to the discoidal nervure, becoming narrowed gradually. Hind 

 legs much longer than the anterior; their coxfe large, calcaria minute, stout,

 L.iiiineriuiii loiigicautla sp. nov. 



Black; the maudibles, palpi and tegulse yellow ; legs fulvous, the coxse black, 

 the trochanters, a broad band on the centre of the hind tibite and the base of the 

 tarsi yellow; the apices of the tarsal joints darker colored; the 4 front tibite 

 tinged with yellow; wiugs hyaline, the nervures fuscous, the areolet small, tri- 

 angular, the pedicle longer than the lower branches, which are equal in length ; 

 the recurrent nervure is received shortly beyond the middle. 9* Length 4; 

 terebra nearly 3 mm. 



Head and thorax smooth, impunctate ; the metanotum aciculated ; there is a 

 minute petiolar area; the areola is horse-shoe shaped, open at the apex, the 

 keels from it are continued round the sides of the metanotum; there are no 

 lateral arese. On the apical half of the mesopleurse in the centre is a deep, 

 slightly oblique, large fovea or depression. 



Hab. -Mexico. 



The long ovipositor, and there being only one area on the meta- 

 notum, distinguishes this species from the other Mexican ones. 



Liinineriiiin leptogaster sp. nov. 



Black, the head and thorax densely covered with silvery pubescence; mandi- 

 bles, palpi, antennal scape below, tegulse, 4 front coxae and posterior trochanters 

 yellow; the rest of the 4 fore-legs yellowish fulvous; the hind coxae black ; the 

 hind femora rufous, their tibiae and tarsi black, the tibiae tinged with testaceous 

 iu the middle; wings short, hyaline, the stigma and nervures blackish, areolet 

 small, with a long pedicle; its basal nervure straight, its apical more curved and 

 broken by a bulla below, the recurrent nervure received beyond the middle. 'J, 

 Length 6 mm. 



Abdomen long, slender, the basal two joints together as long as the thorax ; the 

 2nd, 3rd and 4th segments marked with testaceous at the apex, especially on the 

 sides. The upper part of the head and the thorax closely punctured. Areola 

 long, obliquely narrowed at the base ; there are 2 lateral areae ; the basal is wider 

 than long, obliquely narrowed towards the apex ; the apical is longer and is nar- 

 rowed to a fine point from the inner side at the apex ; the posterior median area 

 is wide at the base, where it is not clearly separated from the areola ; its apical 

 bounding keels are not so strong as they are at the base. Metasternal keel stout. 



Hab. — Mexico. 



This species comes near to L. centrale ; it may be known from it 

 by the much longer abdomen, hirger size, by the posterior median 

 area of the metanotum not being of equal width, but having the 

 basal jiart dilated towards its apex, the rest being also wider above.
