Amorphota relativa, n. sp. 



Closely related to L. (A.) montana, which has the areola and petiolarea 

 bounded laterally by distinct raised lines. 



Female. — Length, 7.5 mm. Head rather shining, somewhat dullish, with 

 indistinctly impressed, separated punctures, less distinct and sparser on the 

 clypeus than elsewhere; cheeks rather shaliowly channeled ; antenna? thirty-six 

 jointed. Thorax with the dorsum dullish, sides rather shining; dorsulum very 

 dull, rather closely punctured, the parapsidal grooves hardly indicated by slight 

 impressions anteriorly; mesopleura distinctly punctured and shining beneath 

 the somewhat triangular impressed area which is smooth and shining and almost 

 impunctate, the shallow channel deeply impressed in the middle, forming a pit; 

 basal area of metanotum almost quadrate, the areola margined only at the base, 

 the channel which occupies the areola and petiolarea shallow, its sides genfly 

 excavated, the margins not at all sharp but gently rounded, lateral areas closely 

 pitted, almost punctured; metapleura distinctively, closely punctured and shin- 

 ing; wings faintly brownish, nearly clear, stigma and nervures dark brown, first 

 abcissa of the radius a little longer than two- thirds of the second abcissa, areolet 

 practically sessile, the petiole almost obsolete, the areolet quadrangular, the first 

 transverse cubitus as long as the second, first abcissa of the cubitus beyond the 

 first transverse cubitus distinctly longer than the succeeding abcissa, transverse 

 median nervure almost exactly interstitial with the basal nervure, second abcissa 

 of the discoidal nervure about two-thirds the length of the recurrent nervure. 

 Abdomen uniformly dullish, very minutely, inconspicuously punctured, the 

 petiole very smooth, no indication of a raised line between the spiracle and the 

 apical margin; exserted portion of ovipositor half as long as the abdomen, the 

 sheaths about a millimeter shorter. Uniformly covered with fine; short, silvery 

 pubescence, longest and most abundant on the face and metathorax. Black; 

 mandibles yellow, brown at tip, palpi cream color; tegula? and base of wings 

 yellowish; anterior and middle legs testaceous, middle femora somewhat rufous, 

 anterior and middle trochanters with the distal joint whitish or yellowish, the 

 tiba? of the four anterior legs whitish on the outer side, tarsi pale, apical joints 

 and claws brownish, posterior legs with the proximal trochanter largely black, 

 the distal trochanter ochreous, femora rufous, tibiae almost whitish with a nar- 

 row brownish band near base, the apical third of the joint brown, metatarsus 

 whitish with the apical third brown, two succeeding joints brown, whitish at 

 extreme base, terminal joints entirely brown, all claws brown and pectinate; 

 ovipositor dark reddish brown, translucent.

Amorphota perrivalis, n. sp. 



Nearly as in L. (A.) major, but areola partly outlined by a basal carina. Re- 

 lated to L. (A.) rivalis, which is smaller and different in various details. 



Female. — Length, 7 mm. Head minutely sculptured ; face dull, rather ru- 

 gulose, indistinctly punctured; cheeks shining, closely, indistinctly punctured; 

 antennae thirty-four jointed, scape and pedicellum distinctly shorter than the 

 first joint of the flagellum Thorax uniformly dull; dorsulum with the parap- 

 sidal grooves represented by faint, rugulose, longitudinal impressions that ter-
