mose band, as shown in the figure (PL 4, fig. 2). The elytra! 

 vestiture is more constant, but in the Washington specimen the 

 white areas although maintaining their position are so reduced 

 in size that the intervening black lines of the striae become ob- 

 vious and the specimen has a much more tessellate appearance. 

 Six of the Milwaukee specimens are females and measure 10.75 

 mm. to 12 mm. while the single male measures 10.25 mm. in 

 length (excl. rostr.).. The fivfe Weiss specimens measure 8.5 mm. 

 (cf and 9) 9.5 mm. (cf 1 ), and 10.5 mm. (tf and 9). The 

 specimens belong in the following cabinets: 



U. S. National Museum, 4 specimens (type and paratype of 

 cattleyarum Bar. and two other specimens from Milwaukee). 



Wisconsin Department of Agriculture, 4 specimens (from 

 Milwaukee) . 



University of Wisconsin, 1 specimen (from Milwaukee). 



American Museum of Natural History, 1 specimen (from 

 Weiss) . 



Mr. Chas. Leng, 1 specimen (from Weiss). 



Mr. E. L. Dickerson, 1 specimen (from Weiss). 



Mr. H. B. Weiss, 2 specimens. 



Cholus forbesii Pascoe 1877. (PL 4, figs. 1, 1A, IB.) 



The specimens in our series are narrower and less roughly 

 sculptured than cattleyae, with the tibial and tarsal vestiture 

 composed of intermixed black and white hairs instead of yellow 

 ones. There are no white scales on the mesopleural plates and 

 the specimens display a different series of elytral and prothoracic 

 squamose markings which vary slightly but in general leave, 

 large, black unclothed areas as follows: A large elongate discal 

 black spot occupying nearly half the length of the suture, and 

 often with lateral extensions near its posterior end; a large thrce- 

 lobed, discal black spot on the pronotum which encroaches slightly 

 on the elytral base on each side of scutellum and is usually 

 narrowly produced anteriorly to join the black head; 1 a pair of 

 post-humeral round spots of about the same size as one of the 

 lobes of the pronotal macula; a pair of subapical lateral spots 

 apparently the same size in the dorsal aspect but produced down- 

 ward and forward to include the posterior coxae ; and finally the 



1 Mr. Champion writes that in the type the white scales of the prono- 

 tuni are more extended partly enclosing three bare patches on the disc, 

 and from a rough diagram accompanying this statement it appears that 

 the prescutellar squamose patch is produced forward and joins with in 

 ward extensions of the transverse squamous hand at basal third of 

 pronotum, leaving the anterior nude area triangular and the basal pair 

 quadrate.
