Illustrations. Drawings were made with the aid of a squared 
grid reticle placed in an eyepiece of a binocular stereomicroscope. 
Illustrations of female structures are made from reproductively 
active specimens or specimens much larger than the smallest repro- 
ductively active one within that species sample. 
Descriptions. Each description is a composite of all the adult 
material at hand with close attention given to the type specimen in 
order to point out any characters for which it is peculiar. Colors are 
described in strong illumination under the low power of the stereomi- 
croscope from a series of specimens which have been dead in 80% 
ethanol for six months to two years. Color changes in Atypoides 
appear to be minimal within this time period. 
Records. Only material that has been personally examined is 
included within the records section. Numbers of immature specimens 
are not recorded; a lack of d or $ symbols means that only im- 
matures were collected at that particular locality. The following 
abbreviations are used for the names of the more frequently cited 
collectors: FAC — F. A. Coyle, JWG — J. W. Gertsch, WJG — 
W. J. Gertsch, WI — W. I vie, VR — V. Roth. 
Morphological terminology. Female genitalia : In Atypoides the 
sperm storage diverticulum opens into the uterus just as the latter 
opens exteriorly at the epigastric furrow (Figs. 78, 79). The epigas- 
tric furrow is between a large anterior lip and a smaller posterior 
lip. On the posterior face of the anterior lip is a more heavily 
sclerotized area which frames and extends inward through the 
transverse ,slit-like opening into the sperm storage diverticulum. This 
thickened cuticle also forms the floor of a rather large chamber 
which will be called the bursa copulatrix. This thickened floor often 
forms paired shallow depressions or ill-defined pockets which possibly 
function in the positioning of the male palpal sclerites. Four trans- 
parent ducts leading from the bases of the seminal receptacles open 
into the very weakly sclerotized roof of the bursa copulatrix. The 
four seminal receptacles are arranged transversely in a single row, 
and are thick-walled and heavily sclerotized except distally where 
they are capped by a rounded thin-walled transparent bulb. The 
proximal narrow part of the heavily sclerotized portion will be called 
the stalk , and the distal expanded part will be termed the bowl
