AKT. L-y WASPS OF SUBFAMILY PSENINAE MALLOCH 59 



PSENIA MINUTA, new species 



Female. — Similar in general habitus to angulwornis but with the 

 abdomen shining black, with rather faint pale apices to the tergites. 

 Structurally the species resembles clavicornis, but the mesopleura is 

 more distinctly punctured, the eps 2 having sparse rather small 

 punctures on the entire surface, which would not be the case if the 

 general rule in the genus held here as the male has that sclerite im- 

 punctate. The enclosure of the propodeum is quite similar to that of 

 aerofacies but smaller and more finely reticulated, and the propodeum 

 outside of the enclosure is very finely striate, even on the posterior 

 face, the striae diverging from the central impression to each side 

 and almost without connecting reticulations. The pygidium is a 

 little- wider than in anffulicon^ls, being about as in tibi-ah's. Inter- 

 carinal space narrow, the occipital carina complete but not promi- 

 nent. Legs and wings normal. Petiole not as long as remainder 

 of segment. 



Length, 5.5 mm. 



Ti/pe.—U.S.^M. No. 44230, from San Diego. Tex., May 16 (Ash- 

 mead collection).
