108 Mr. A. Hempel on Brazilian Coccide. 
Genus PsEUDISCHNASPIS, Hempel. 
The adult female scale brown, flat, long and narrow, with 
a superficial resemblance to Jschnaspis. Pellicles orange, 
not overlapping, placed at the extreme anterior end of the 
scale. Male scale similar in shape and structure to that 
of the female, but much shorter. ‘The pygidium of the adult 
female has three well-defined lobes and body-thickenings, 
as in Chrysomphalus. Four groups of circumgenital glands 
are present. No reticulated area on the dorsum of the 
pygidium. 
Type Pseudischnaspis linearis, Hempel. 
Pseudischnaspis linearis, Hempel. 
Female scale elongate, narrow, flat; sides parallel; the 
posterior end sometimes obliquely truncated; dark brown in 
colour. The pellicles are orange in colour and are placed at 
the anterior end. The first pellicle is darker than the second, 
with a small central ring on the dorsum. Length 2-3 millim.; 
width °75 millim. 
Male scale lighter in colour, but of the same texture and 
shape as the female scale. Length 1°25 millim.; width 
30 millim. 
Adult female elongate, flat, white; pygidium with three 
pair of well-developed lobes, the median pair narrowest, the 
third pair the widest. The posterior edge of the median pair 
is entire or slightly notched, but the edge of the second and 
third pair is serrated. There are six pair of elongate thick- 
enings of the body-wall at the base of the lobes, arranged in 
the following manner :—the median pair short, the next long, 
the next short, the next longer, the next long, and the last 
short. Between the median lobes there is a deeply incised 
bifid plate ; between the median and second pair of lobes there 
is a deeply incised plate ; between the second and third pair 
of lobes there are two plates and one hair, and laterad of the 
third pair of lobes there are two or three plates and one hair. 
The lateral margin is chitinized and notched and serrated 
laterad of the third pair of lobes. Four pair of circumgenital 
glands are present. ‘The anterior laterals vary from six to 
eight, the posterior laterals from four to seven. The anal 
orifice is situated on a plane between the posterior groups of 
glands. The pygidium bears numerous long, fine, tubular 
glands. Some of these glands are also found on the other 
abdominal segments. ‘lhe antennz are present as small 
tubercles with a long curved hair. ‘The derm is transversely 
striated, and bears a few hairs.
