Subtribe CERVAPKIDr>7A. 
The subtribe Cervaphidina is a most interesting and peculiar one. 
The specialization is remarkable in that long processes are developed 
on the body and considerable reduction has taken place in the wings 
and antennae while no Aphis-like Cauda is found. Only two genera 
are known, which may be separated as follows: 
# IvET TO THE (tEXEKA OF THE < ERVAIHEDIXA. 
Cornicles swollen; body spine-like projections not armed with teeth. . .Anonialaphis. 
Cornicles not swollen: body spine-like projections armed with teeth Cervaphis. 
Genus ANOMALAPHIS, n. gen. 
Plate VIII. D-F. 
Characters. — Body armed with elongate tubercle-like projections, particularly on 
the caudal portion; antennae five-segmented in both apterous and alate forms, 
armed with subcircular sensoria. Fore wings with the media once branched; 
hind wings considerably reduced, with the cubitus absent. Cornicles distinctly 
swollen; cauda and anal plate reduced. 
Type Anomalaphis comperei Pergande. 
Anomalaphis comperei Pergande. n. sp. 
Among the many descriptive notes left by Mr. Theo. Pergande are 
some recording a peculiar species from Australia. This proves to 
represent an undescribed genus in the Cervaphidina. Pergande rec- 
ognized the species as typical of a new genus to which he gave the 
manuscript name here used. He left no description of the genus 
and his notes on the species are given here exactly as he left them. 
The type is in the United States National Museum collection of 
Aphididae (Cat. No. 23065). 
Feb. IS, 1907, Rec. from Compere, a lot of Aphides, found in 1901, on Acacia and 
Eucalyptus, along the beach at Albany, West Australia, which represents a new genus 
among Rhopalosiphins, and is a most remarkable Aphid in various respects. The 
antenna?, in the apterous and migratory female, are but 5-jtecI. while the spur is rather 
short and resembles that of Chaitophorus. The front wings are ample and reach con- 
siderably beyond the end of the body, with the thud discoidal having but one fork, 
as in Schizoneura. The hind wings are very short and narrow and reach out to the 
apex of the 1st vein of the anterior wings, there is also but 1 discoidal, straight, and 
near the apex of the wing. The nectaries are short, clavate, and similar to those of 
Siphocoryne, the tail appears to be wanting. The abdomen of the migrant appears 
to have been of a dusky yellowish green, with transverse rows of small, black spots or 
tubercles, and blackish sutures between the segments. The eyes are brown; antennas 
black, rather short, reaching barely to the abdomen and but 5-jointed; the two basal 
joints as usually; the 3rd joint is longest, about as long as the remaining joints together, 
including the spur, with some projecting sensoria and a few short hairs; joints 4 and 5 
are subequal in length, exclusive of the spur, and clavate, the spur is about \ the 
length of the basal section of the joint, rather stout and blunt; the front of the 
head resembles that of Aphis. The sides of the abdominal segments are somewhat 
angulated, each angle provided with a very short, capitate, stout bristle, while at the 
posterior edge of the two segments, following the nectaries, there is a pair of long,
