1942] Genus of Cimicoidea from Baltic Amber 45 
important characters are: ocelli distinct, rostrum three-seg- 
mented, membrane with four free longitudinal veins, ostiolar 
canals absent, tarsi two-segmented, claws without arolia, 
spiracles two to seven ventral, seventh abdominal sternite cleft 
in the female. No mention is made of trichobothria. Obviously, 
Electro cor is is not to be confused with Joppeicus , but the sys- 
tematic position of the latter should be studied carefully in 
any review of hemipterous phylogeny. 
Electrocoris brunneus new species 
Figure 1 
Male. Body clothed with a rather short pubescence. Head 
moderately declivous, the gula about as long as buccal open- 
ing. Antennae robust, proportion of segments one to four as 
5:15:11:16. Legs relatively stout. Color of body uniformly 
light brown. Length 3.12 mm. 
Female. Similar to male except for the genitalic differences 
described above, the slightly longer apical antennal segment 
(proportion of segments one to four as 5:15:11:18), and the 
shorter, more robust body form (length 2.51 mm. in the allo- 
type and approximately the same in two partially obscured 
paratypes).

one paratype retained in my collection. 
Electrocoris pubescens new species 
Female. Body clothed with a relatively longer, fine, dense 
pubescence. Head only feebly declivous, the gular region over 
twice as long as buccal opening. Antennae relatively slender, 
the proportion of segments one and two, 4:: 18, the apical 
segments broken off. Legs and particularly tarsi slender. Color 
of hemelytra dark brown, of body beneath, dark brown or 
nearly black with posterior margins of ventral segments pale. 
Length 2.5 mm.

Pubescens , though obviously related to brunneus , is strik- 
ingly distinct, the longer and denser pubescence, more porrect 
head, and darker color immediately setting it apart. Both of
