Chapin — Pseudoscymnus 
51 
wide as eighth, subconical. The ninth segment bears at its apex 
several long setae. Maxillary palp with the three segments nearly 
equal in width, the terminal segment parallel-sided with apex sharply 
oblique. Terminal segment of labial palp stout barrel-shaped with 
truncate apex. Mandible with subapical tooth. Prosternum not 
produced anteriorly to cover mouthparts, prosternal lobe rather 
narrow, carinate. Abdomen with six visible sternites. Coxal arc 
incomplete, much as in Nephus Mulsant. Tibiae simple, rather 
slender. Tibial spurs absent. Tarsus three segmented. Claw with 
subquadrate basal tooth. Elytral epipleura nearly flat and horizontal, 
not distinctly foveolate. 
Male — aedeagus symmetrical. 
Female — receptaculum seminis with ramus short and stout, 
nodulus long, drawn out in a slender, curved tube, or short and 
stout, cornu curved, sausage-shaped. Sperm duct very short if nodulus 
is elongate tubular, otherwise moderately long. Infundibulum absent. 
Hemisternites intermediate between the “blade and handle” type of 
the majority of the Coccinellidae and the “ovipositor” type of most 
of the Scymnini. 
Type-species — Scyrnnus hareja Weise. 
I am including the following species in Pseudoscymnus — 
Pseudoscymnus hareja (Ws.) 1879, Deutsch. ent. Zeit., 23: 150; 
Miyatake, 1958, Japanese Journ. Appl. Ent. Zool., 2:251- 
256. figs. 1 A-D, 3 A-B, 4 E-H, 5 A-C. 
Pseudoscymnus kurohime (Miyatake) 1959, Mem. Ehime Univ., 
(6) 4: 136-138, figs. 50-61. 
It is probable that the following four species also should be referred 
to Pseudoscymnus — 
Scyrnnus seboshii Ohta 1929, Ins. Matsumurana, 4: 1 1 ; 
Miyatake, 1958, Japanese Journ. Appl. Ent. Zool., 2:251- 
256, figs. 2 A-C, 3 C-D, 4 A-D, 5 D-F. 
Scyrnnus sylvaticus Lewis 1896, Ann. Mag. Nat. Hist., (6) 
77:36; Bielawski 1957, Trans. Shikoku Ent. Soc., 5:71, 
figs. 5-1 1. 
Scyrnnus pilicrepus Lewis 1896, op. cit., p. 36; Bielawski, 1957, 
op. cit., p. 72-73, figs. 12-15. 
Scyrnnus quinquepunctatus Weise, 1923, Arch. Naturg., 89.
