Neiv Species of Ceroplatus 
21 
band at base, remainder is yellow. Tibia and basi tarsus 
yellow. Tibia about .7 as long as the basi tarsus. Remain- 
der of tarsus appears dark because of presence of setulss. 
Coxa of mesothoracic leg yellow except for brown band on 
the outer anterior surface and a narrow black stripe at the 
distal portion. Trochanter yellow. Femur with a narrow 
brown band at the base, the remainder yellow. Tibia and 
tarsi yellow but covered with black setulse. Coxa of meta- 
thoracic leg resembles that of the mesothoracic leg except 
that the brown area is larger. The rest of the leg is the 
same in appearance as the mesothoracic appendage. 
Abdomen. Dorsum of segment one entirely dark brown. 
Segments two through five have the dorsum dark brown 
except for a posterior lateral yellow spot on either side. 
Ventral portion of abdomen yellow. Hypopygium dark 
brown, resembles somewhat that of Ceroplatus militaris 
Johannsen. It can be distinguished from that of Johann- 
sen’s species by the lack of dense clusters of black setae on 
the inner and dorsal surfaces of the base of the disti-style. 
This new species would run to Ceroplatus militaris in 
Johannsen’s key. It can be distinguished from militaris 
by the structure of the hypopygium, as already discussed; 
by the relative lengths of the fused portion of veins M and 
R and the petiole of media ; and by the markings. 
Described from one male taken in September 1940, at 
Fernald Hall, Massachusetts State College, Amherst, Massa- 
chusetts by Dr. C. P. Alexander. Type in my collection.
