two new Coccide from New Mexico. 405 
hair. End of tibia with a stiff bristle on inner side. Claw 
rather short, curved. 
Anal ring with six very distinct hairs. Posterior tubercles 
inconspicuous, each emitting a hair similar to that on the anal 
ring. 
Sides of body with many round gland-spots, and margin 
with pairs of short spines at intervals, at least on the posterior 
part of the body. 
Lower lip elongated as in Orthezia, with about ten hairs. 
Rostral filaments short. 
After boiling in caustic soda the insects appear pale reddish 
brown or almost colourless ; they do not appreciably stain the 
liquid. 
The above description refers to the adult female; larve 
‘ were found with them in June 1893, but the male is as yet 
unknown. 
Hab. In the main street of Las Cruces, on leaves of 
Fouquiera. 
When I first examined this insect I supposed it might be 
identical with the Scgaoretia sp. recorded by Prof. Townsend 
as found on Larrea; but I now doubt whether this is the 
case. It is certainly not a species of Signoretia, Targ.-Tozz., 
although as found living it has much superficial resemblance 
to S. atriplicis as figured by Maskell. It does, however, 
appear to be a Szgnoretia, Kraatz, which is the same as West- 
woodia, Sign., and Bergrothia, Kraatz—the first two names 
being preoccupied. Maskell would not separate Bergrothia 
from Dactylopius, and certainly it is difficult to draw any satis- 
factory line between these genera, owing to the number of aber- 
rant Dactylopius spp. described by him and others of late years. 
The present species, though placed in Bergrothia, does not 
agree in all respects with the accepted definition of that genus, 
but it is much further removed from typical Dactylopius. 
This is the first of its genus to be described from North 
America; but an unnamed species has been mentioned as 
occurring on blue-grass in Indiana &e. (‘Insect Life,’ ii. 
p- 327).
