minate posteriorly in a rugulose area in the middle of the posterior third of the 

 segment, the adjoining areas very minutely sculptured ; mesopleura sculptured 

 like the greater part of the dorsulum, with a very shallow oblique groove that is 

 finely striate and dull like the adjoining areas, a small pit in the middle of the 

 posterior half of the segment; metanotum rather coarsely rugulose, basal area 

 forming almost an equilateral triangle, areola pentagonal if completed, the lateral 

 angles very near the base, the sides parallel, the areola a little more than twice 

 as long as wide, petiolarea ill defined, very broad angled above the middle, almost 

 as broad as long; wings nearly as in the preceding species, areolet petiolate, 

 quadrangular, the petiole as long as the shortest side of the areolet, first trans- 

 verse cubitus a little shorter than the second, first abcissa of the cubitus beyond 

 the first transverse cubitus as long as the transverse cubitus between the petiole 

 and the cubitus, cubitodiscoidal nervure with a slight elbow just before the 

 middle, transverse median nervure a little beyond interstitial with the basal 

 nervure, second abcissa of the discoidal nervure nearly two thirds the length of 

 the recurrent nervure. Abdomen sculptured as in the preceding species. Uni- 

 formly covered with short, fine, silvery hairs which are tinted with golden on the 

 dorsum. Black; scape and pedicellum ochreous beneath, brown above; mandi- 

 bles yellow brown at tip; palpi, tegulse and base of wings yellowish; coxae and 

 trochanters of anterior legs and trochanters of middle legs yellowish, remainder 

 of anterior and middle legs testaceous, except the outer side of the tibi^ which 

 are whitish, the apical tarsal joint and claws of anterior and middle legs brown, 

 tibiae and femora of the middle legs with a rufous tint, posterior legs rufous, the 

 tibiee more or less brownish, the tarsi and claws dark brown; abdomen rufous, 

 basal half of petiole blackish, venter yellowish, exserted portion of ovipositor 

 about as long as the second abdominal segment, the sheaths a little shorter, ovi- 

 positor translucent, brown, sheaths black.

 Amorphota nocturna, n. ep. 



Superficially like dubitatus, from which it differs in the structure of the 



metanotum. 



Male.— Length, 5.5 mm. Head minutely sculptured ; cheeks somewhat shin- 

 in a-, very minutely roughened; face dull, very closely sculptured; antennjB thirty- 

 three jointed, scape and pedicellum together as long as the first joint of the 

 flagellum, or a little longer. Thorax largely dull; dorsulum very closely sculp- 

 tured, the parapsidal grooves represented by very shallow grooves that are more 

 coarsely sculptured than the adjoining area, mesopleura almost bisected by a 

 transverse, faint, sinuate, roughened impression or groove, the depressed portion 

 of the superior half of the segment largely smooth and shining; scutellum and 

 metathorax sculptured much like the dorsulum, basal area nearly quadrate, shin- 

 ing, areola pentagonal, the sides almost equal in length ; petiolarea confluent 

 with the areola, about twice as long as broad, angled near the middle, the sides 

 below the middle not well defined, the lower half of the petiolarea and the apical 

 lateral area rugulose; metapleura closely, indistinctly punctured and somewhat 

 shining ; wings faintly brownish, stigma pale brown, nervures darker, first abcissa
