Eriophyes ramosus n. sp. An interesting infestation by eriophyid mites was 
brought to my attention by Dr. E. P. Felt on a specimen of Juniperus pachyphlcea 
from Williams, Arizona. The juniper was received from Prof. E. Bethel, State 
Museum, Denver, Colorado. 
The twig bore several large, more or less deformed, infertile fruits. On the surface 
of each were several minute circular openings. Upon dissection, the berries w T ere 
found to be literally alive with the mites which had entirely destroyed the inner 
cellular structures. In some of the fruits the creatures were so abundant that their 
bodies entirely filled the cavity. 
A similar injury has been mentioned by Dr. A. Nalepa on Juniperus communis L. 
in Europe and is said to be caused by E. quadrisetus typicus (F. Thom.). The Ameri¬ 
can form differs in several respects from the foregoing species and may be recognized 
by the following characters: 
The body is small, cylindrical, uniform in width, and very long. Length 231ju, 
width 59^. 
The thoracic shield is small, triangular in form and slightly arched. Its lateral 
margins are gently rounded and partially cover the trochanter. The anterior margin 
is acuminate and projects over the rostrum, while the posterior margin is gently 
rounded. The dorsal setae are longer than the shield, rather fine and are usually 
directed anteriorly. The setal tubercles are of medium size, nipple like, being 
situated widely apart near the posterior margin but not projecting beyond. The 
rostrum is of medium length, stout, strongly curved, and projecting forward and 
obliquely downward. The rostral bristles are long and stout. The claw is truncate, 
curved, slightly shorter than the feathered hair which is 9-rayed and very strong. 
The thoracic setse are all present. T. setae I are very long, and placed at some 
distance from the anterior end of sternum. T. setae II are very long, widely separated 
and situated opposite the inner epimeral angles. T. setae III are of medium length 
and situated about midway between the inner and outer epimeral angles. 
The abdomen is cylindrical, having 72 striae which are finely punctured along the 
posterior margin. The dorsum and ventrum are similar in character. The setce 
are all present. The Lateral setae are about equal to Ventral setae I in length; the 
Genital setae are of medium length and stout; setae Ventral I are of medium length, 
fine and do not appear to overreach setae Ventral II; setae Ventral II are longer than 
the genital setae; setae Ventral III are very stout, reaching the ventral lobes. The 
accessory and caudal setae are present, each pair being very long and stout. The 
epigynium is wide, semicircular and has a coarse distinct sculpturing on the epigynial 
plate. 
Superficially these mites may be recognized by a pinkish to dark-red coloration 
and the great length and narrowness of the body.

Nicotine Sulphate an Effective Ovicide for Codling Moth Eggs. Following the 
remarkable results of F. E. De Sellem 1 of N. Yakima, Washington, with nicotine sul¬ 
phate as a control for codling moth, experiments have been undertaken seeking to 
throw additional light on the subject and afford a satisfactory explanation of the
