One specimen, No. A5S, collected by Mr. S. A. Rohwer at Station 14. 

 Type in the Amer. Mils. Nat. Hist. 



This is a very typical species of Limnerium in all respects and 

 appears to be a close relative of some living forms. 



Limnerium consuetum, sp. nov. (Fig. 59.) 



Female. Length 5 mm. Dark colored, reddish on the abdomen below from 

 the third segment to the tip; legs yellowish, the posterior pair darker. An- 

 tennae rather short, slender, particularly near the base of the flagellum. 

 The number of joints is not plain, but there are apparently fewer than in the 

 other species here described. Surface of thorax roughly shagreened or punctu- 

 late, the metanotum arcuately rounded behind and not completely areolated 

 although the pleural areas 

 are strongly marked and the 

 lateral ones indistinctly sepa- 

 rated. Abdomen slender at 

 the base, but strongly com- 

 pressed apically, its surface 

 coriaceous. Petiole as long 

 as the entire slope of the 

 metathorax, slender at the 

 base and clavately thickened 

 apically; second segment 

 very long, a little longer than 

 the first; third shorter, but 

 still a little longer than its 

 height at the tip. Following 

 segments strongly com- 

 pressed. Ovipositor issuing from the base of the sixth segment, as long as 

 the abdomen exclusive of the first three segments. Wings hyaline; stigma 

 dark brown and veins pale brown ; stigma rather slender, two-fifths as wide 

 as the marginal cell which is somewhat broader than in the other species. 

 Areolet triangular, large, its upper point touching the radius; second section 

 of the radius about twice as long as the first. Median and submedian cells of 

 approximately equal length. 



One specimen, No. A112, collected at Station 14 and sent by Pro- 

 fessor Cockerell. Type in the Amer. Mus. Nat. Hist. 

 This is a typical species of the genus.
