134 Psyche [March-June 
Dineparmene gen. nov. 
(fig. 16) 
Vertex a little longer than wide, lateral margins diverging 
basally, posterior margin very shallowly excavate, anterior mar- 
gin transverse curving uninterruptedly into frons; lateral mar- 
gins carinate, median carina distinct to base and passing an- 
teriorly into median carina of frons, no transverse carina; frons 
longer than broad ( 1 .4 to 1 ) , lateral margins expanding distally 
not narrowing to suture, or scarcely so; greatest width of frons 
below level of antennae; width at base slightly more than half 
width at apex; median carina present throughout, no median 
ocellus; clypeus at base scarcely as wide as widest part of frons, 
flattened, weakly carinate medially, lateral margins carinate; 
vertex and basal half of frons forming in profile an even curve, 
apical half of frons feebly convex, suture impressed; genae 
somewhat tumid; antennae with basal segment very short, ring- 
like, second segment slightly longer than broad. Pronotum as 
long as vertex, posterior border shallowly excavated, sloping 
obliquely anteriorly near sides; median carina distinct, no lat- 
eral carinae on disc, lateral margins carinate between eye and 
tegula; mesonotum convex, strongly tricarinate, scutellar area 
much depressed; posttibiae unarmed. Abdomen with wax-bear- 
ing plates rather prominent. 
Tegmina with sides subparallel; Sc+R forking near stigma, 
a short Sc+R+M stem basally, nine cells on apical margin. 
Wings with fourth apical cell about three times as long as its 
basal stalk. 
Genotype, Eparmene cubana Myers 1928, Studies on Cuban 
Insects: 20. 
This genus has the wax-bearing surfaces of the abdomen de- 
veloped to a larger size than seems to be usual in Prosotropinae. 
It differs from Eparmene Fowler in having the frons reaching 
its greatest width below the level of the antennae, the maximum 
width in Eparmene being reached at the upper level of the an- 
tennae; in having the basal joint of the antennae very short, this 
being unusually long in Eparmene , and in not having a tricari- 
nate pronotum. The description has been drawn up from the 
monotype with the original description at hand. It is worth 
recording that the waxy secretion of D. cubana is unusual in 
taking the form of curved thick parallel rods, which are trans- 
lucent and opalescent.
