p. 68) has recorded his rediscovery of the lost species, Cylapus tenuicornis, described 
by Say, and has given an excellent figure of the same. For the reception of this species 
Say proposed the generic name Cylapus. From a comparison of Mr. Heidemann’s 
figure with those representing species of Stal’s genus Valdasus in this work, Prof. Uhler 
(ibid. p. 123) has rightly concluded that the two genera are synonymous, and that, 
despite Say’s very meagre diagnosis, the name Cyl/apus must take precedence.

Prof. Uhler (Proc. Ent. Soc. Wash. 1891, p. 123) has expressed his opinion that this . 
species is really the Cylapus tenuicornis, Say, and that therefore Stal’s species must sink 
as asynonym of the same. I was, however, fortunately enabled to figure the type of 
C. famularis in this work (Tab. XXIV. fig. 7), and from a comparison of this with 
Mr. Heidemann’s figure of the North-American species described by Say, I am unable 
to share Prof. Uhler’s opinion. The Mexican species thus appears more elongate and 
narrow, and the difference of markings may be seen in the corresponding presence and 
absence of the pale marginal spots to the pronotum of C. tenuicornis and the apical 
claval spot in C. famularis. The markings of the scutellum, corium, aud cuneus are 
also different in the two species.
