126 ME. W. H. ASHMEAT* ON THE PAEASITIC HTMENOPTEEA 



more or less tinged with yellow ; tlie first branch of the radius 

 equal to the second, or very slightly longer ; the first transverse 

 cubital nervure is not interstitial with the recurrent nervure, but 

 joins the cubital nervure. Abdomen of three segments, the first 

 and last about equal, the second the shortest, all striate-rugose. 



Hab. St. Vincent. 



Described from five specimens, taken at an altitude of 500 feet. 

 The species is near P. huineralis; but the distinct parapsidal 

 furrows, the length of the first branch of the radius, and in that 

 the first transverse cubital nervure joins the cubital nervure, 

 separate it at once from the foregoing and the following species. 



PHiENOTOMA rUSCOTAEIA, Sp. n. 



S $ . Length 2^ to 4 millim. Pale ferruginous or honey- 

 yellow, finely rugose-punctate, with variable fuscous markings j 

 sometimes it is wholly pale, with only the apex of the antennae 

 and the abdomen fuscous ; sometimes there is a central fuscous 

 stripe on the mesonotum, metathorax, and abdomen, the scu- 

 tellum being wholly fuscoiis ; sometimes the mesopleura, meta- 

 thorax, tip of abdomen, apex of posterior tibise and their tarsi 

 are dusky or fuscous, although usually the legs are of a uniform 

 pale colour. Wings greyish-hyaline, the venation brown ; the 

 first and second branches of the radius about equal in length, 

 while the first cubital nervure is always interstitial with the 

 recurrent nervure. Abdomen of three segments, the first and 

 third segments about equal, the second a little shorter, all striate- 

 rugose, the first with two distinct keels above. 



Sab. St. Vincent. 



Described from 31 specimens. 



Chelonus, Jurine. 



CHELONt'S MEEIDIONALIS, sp. U. 



S $ . Length 2| to 3 millim. Black, rugose, covered with a 

 sparse, sericeous pubescence. Antennae 16-jointed, the two basal 

 joints yellowish, or at least beneath. Thorax, in the middle pos- 

 teriorly, coarsely rugose. Scutellum smooth, polished, with a 

 row of coarse punctures across the base. Metathorax with two 

 median keels connected with a keel on the superior edge of the 

 posterior face, the augles slightly prominent. Legs honey -yellow, 

 all coxse, middle and posterior femora, the apical half of their 

 tibise, and four apical joints of their tarsi black or fuscous.
