of these as new. Following these descriptions I will present a general 
account of the two larval specimens. 
Propsychopsis helmi Kruger 
Propsychopsis helmi Kruger, 1923, Stett. Ent. Zeit. 84: 84-85. Type speci- 
men stated to be in the Danzig Museum, not examined. 
Discussion. Kruger mentions the presence of about 40 costal cross 
veins and about 25 cross veins in each of the cells between Sc and Ri 
and between Ri and Rs. All of these counts are higher than in 
the specimens now at hand and it is possible that these characters 
may provide the means of subsequently identifying P. helmi when 
additional material is discovered. These particular venational fea- 
tures, however, are quite variable and new material could also show 
these characters to have no taxonomic importance in Propsychopsis. 
Kruger made no mention of any wing pattern in his description, but 
as he seldom mentioned any features other than the venation in his 
treatment of any species, living or fossil, his omission in this case 
is probably of no significance. 
Propsychopsis lapicidae n. sp. 
(figs. 8-10) 
Description. Antenna with about 30 flagellomeres distal to pedicel. 
Fore wing with 33-35 costals proximal to end of vena triplica; 16-17 
branches to Rs (not including MA) ; terminal (outer) gradate 
series complete; with a pattern (fig. 9) of two large spots along 
length of Cu and a third across MP distally, with additional similar- 
sized dark spots in the middle of the discal gradate series and along 
vena triplica, elsewhere smaller, paler spots and blotches. Hind wing 
with 10-11 branches to Rs, two gradate series; membrane patterned 
with faint irrorations. Male genitalia (fig. 10) with the ectoprocts 
produced posteriorly, presenting a rounded triangular outline in 
lateral view; mediuncus (arcessus of Tjeder, i960) elongate, parallel 
sided basally, then tapering to a long triangular point. 
Holotype, male: right fore wing with 33 costal veinlets, 17 
branches to Rs; length approximately 13 mm (tip missing) ; right 
hind wing with 10 branches to Rs. The specimen is oriented with 
all four wings spread in a thin piece of yellow amber which, except 
for one rounded corner, is rectangular in shape. This insect was 
apparently subject to some decay before complete entombment, as 
the ventral half of the head and thorax, including the legs, are 
missing. In addition much of the tip of the left fore wing is gone
