AN ANNECTENT GENUS OF CIMICOIDEA FROM 
BALTIC AMBER (HEMIPTERA) 
By Robert L. Usinger 
University of California, Davis, California 
Among the Hemiptera in the Haren collection of Baltic amber 
insects submitted to me for study by Dr. F. M. Carpenter were 
five anomalous specimens of the superfamily Cimicoidea. Al- 
though bearing a superficial resemblance to certain Miridse in 
body form and general facies, closer study disclosed several 
aberrant characters which suggest relationship with the Micro- 
physid-Anthocorid complex. Actually these specimens do not 
fit any family as recognized at the present time and hence must 
assume a place among the annectent Cimicoidea made famous 
in recent years by Bergroth (1924, 1925), McAtee and Malloch 
(1924, 1926) , and China and Myers (1929). Fortunately, some 
of these specimens are so beautifully preserved that structural 
details are more readily observed than would be the case with 
pinned specimens. The points still to be desired would be an 
unobstructed dorsal and ventral view, a clear view of the veins 
of the hind wings and a cleared dissection of the male genitalia. 
All other features show up as clearly as though the specimens 
had been mounted in Canada balsam. 
Electrocoris new genus 
Elongate-oval and moderately robust in body form, suggest- 
ing a Bryocorine Mirid at first glance. Head scarcely to mod- 
erately deflexed, the upper surface evenly arcuate from base of 
vertex to apex of clypeus and the gula well developed, as long 
or longer than buccal opening. Eyes broadly contiguous with 
pronotum. Ocelli distinct, located laterally on vertex well back
