In ANNALS ENT. Soc. AMERICA, 1911, p. 48 the type of the 
species was referred tentatively to A. aedipes Bollman, but 
study of the type of the latter shows it to be clearly distinct. 
Genus Gosibius Chamberlin. 
Gosibius monicus sp. nov. 
Dorsum brown, with a darker median longitudinal stripe which 
shows a marked tendency to spread laterally at the caudal end of each 
plate and often reaches the lateral margins across the caudal border. 
Head ferruginous; the median longitudinal stripe of dorsum continuing 
forward upon the head as far as a little caudad of the frontal suture 
where it ends abruptly at a pale transverse band. Antenne ferruginous. 
Prosternum and prehensorial feet pale ferruginous. Venter yellow or 
testaceous, the caudal segments darker, more reddish or ferruginous. 
Legs yellow or testaceous like the venter, nearly uniform, or the caudal 
pairs slightly darker dorsally. 
Head subcordate, wider than long in about ratio 47: 45. Caudal 
margin mesally gently incurved; sides conspicuously converging from the 
lateral interruptions caudad about the rounded corners. A median 
longitudinal sulcus extending forward from frontal suture to a trans- 
verse depression between the antenna, narrow and not very deep. A 
short, deep, transverse sulcus a little in front of median portion of caudal 
margin, the same being more weakly indicated farther laterad on each 
side. Smooth and shining, not punctate or roughened. 
First dorsal plate smooth and shining like the head, or very ob- 
scurely roughened. Other dorsal plates more or less roughened, the 
more caudal ones most strongly so. Major plates with the short 
transverse sulcus adjacent to each lateral margin at about one-third 
its length from caudal end, the seventh having in addition a similar 
sulcus near the middle of length. A median longitudinal furrow on 
each side between middle and lateral margin which may be indistinct, 
especially on caudal portion of plate; this furrow at about beginning of 
middle third of length sending off a more clearly impressed branch 
directly mesad which may be united with the corresponding furrow 
from the other side; often a short sulcus running from near anterior 
margin obliquely ecto-caudad toward point of origin of this transverse 
furrow. 
Ventral plates apparently smooth and shining; the usual three 
longitudinal impressions indicated in varying degrees of distinctness. 
On several of the caudal plates the median furrow may end caudad in a 
deeper, pit-like and somewhat transverse, depression a little in front of 
caudal margin of plate. 
Antenne long. In types tips are broken off so that full number of 
articles can not be ascertained; but the number present indicates that 
the full number is somewhere above 29. 
Eyes in types from 15 to 17 in number, arranged in four series; 
thus, 1+4 (5), 4, 4, 2: 1+4, 4, 4 (3), 4.
