WASP-GENUS PARALASTOR. 601 
minutissina inter puncta majora densa. Frons capitis cum 
thorace brevissime pilosus. Mesonotum nitidum, densissime, 
‘ortiter punctatum, scutello inermi, tegulis grosse et profunde 
vunctatis. Abdominis segmentum primum latissimum, fortiter 
punctatum, pubescentia minutissima decumbente excepta, fere 
nudum; segmentum secundum fortiter convexim elevatum, pilis 
erectis carens, distincte crebreque punctatum. Segmentum 2 
ventrale post sulcum sat abrupte, sed minus fortiter, supra partem 
suam basalem elevatum, elevatione summa quasi incrassationem 
transversam formante, post hane depressum et subtilius nec dense 
punctatum ; segmentum ultimum pilis erectis evidenter vestitum, 
leviter convexum, et subtiliter, nec dense, punctatum. Ale fere 
hyaline, costali parte conspicue infuseata. Long. circiter 7 mm.

56. PARALASTOR MACULIVENTRIS Sauss. 
I think it probable that this species may be identical with my 
P. elegans, described above. Saussure says nothing of the strongly 
raised elongate clypeal carine, which Mr. Meade- Waldo informs 
me occur in Saussure’s ty pe, as in P. elegans. He also informs 
me that the type specimen is deformed, the sides of the face being 
asymmetrical. The only difference, so far as I can judge, between 
the two forms is that in P. maculiventris the apical band of the 
first abdominal segment is entire, not disappearing before it 
attains the lateral angles, that the head is said to be covered with 
a blackish tomentum (pale in P. elegans, and conspicuously golden 
in front), the ‘inner borders of the eyes are yellow” (only a 
yellow spot in the sinus in P. elegans), while the latter has the 
postscutellum hardly perceptibly tuberculate.
