The specimens I have examined present no particularly interesting- 

 variations. Dr. LeConte, "in Proc. Am. Philos. Soc. xvii, 427, mentions 

 a variety from Florida, in which the bands are narrower, and which 

 varies slightly in other respects from the type form. 



14. M. uiidulata Mels. Pr. Ac. Nat. Se. Phila. ii. 316. (PI. II, fig. 7). 

 Apparently very rare ; I have seen only a single specimen from 



Dr. LeContes collection and this seems to present nothing especially 

 noteworthy. 



15. Ifl. fascifera Lee. Pr. Am. Philos. Soc. xvii, 427. (PL II, fig. 8). 

 I have seen the type and from it the figure was made. 



16. M. discoidea Mels. Pr. Ac. Nat. Se. Phila. ii, 315. (PL II, fig. 9). 



The smallest and prettiest of our species of this genus. It is rare, 

 and I have found but a single specimen^, and that on Long Island ; the 

 figure is made from that specimen ; there is said to be a variety with 

 only two transverse bands on the elytra, but this I have not seen. 



GL.1 l-OIM.S Lee. 



Species cuneiform ; narrow, fuscous, covered with dense sericeous 

 brown pubescence. Scutel rounded, triangular ; anal style moderately 

 long ; hind tibia without subapical ridge ; carinate along dorsal line and 

 furnished with a long oblique ridge on outer surface, connected with 

 dorsal ridge near tip ; first joint of hind tarsi with two oblique ridges ; 

 eyes coarsely granulated ; antennae feebly serrate. Last joint of maxillary 

 palpi scalene, triangular. 



Very unsatisfactorily separated from MordeUistena by the characters 

 given in the description of the genus. There are only two species known, 

 and they resemble each other very closely so far as superficial appear- 

 ance is concerned. In the % of G. sericans Mels. the maxillary palpi are 

 covered on the under surface with a dense brush of fine short hair; in 

 the same sex there is at the base of the last joint an external articulated 

 bifurcated appendage the branches of which are as long as the joint ; no 

 trace of this is seen in the 9 . For tibia and tarsi see PI. II, fig. 10. 



A. — Labial palpi with last joint emarginate. 



Cuneiform, elongate, fuscous, densely clothed with sericeous brown pubescence. 



6 — 8 mm.; Middle and Southern States 1. sericans. 



B. — Labial palpi witli the last joint truncate. 



Almost linear: fuscous, densely clothed with sericeous brown pubescence. 

 4.5 mm.: Georgia , 2. lielva.
