376 Mr. Kxrby's Century of Insects. 



and learned friend M. Latreille, in adhering to which I liave 

 found that my cabinet contained many insects that could not 

 well be placed in any of his present genera. These I have named 

 and characterized. 



COLEOPTERA pentamera. 



{Cicindelidce.) 



Megacephala Latreille. 



brasiliensls. 1. M. viridis, elytris dorso nigro : macula apicis, ore, 

 pedibusque rufescentibus. 



Long. corp. lin. 8§ — 9- 



Habitat in Brasilia. D. Hancock. 

 M.Carolina simillima, sed minus nitida. Thorax dorso nigrescit. 



Elytra nigra: margine laterali tantum viridi; macula apicis 



lineari rufa, nee apex ipse pallidus ut in ilia. 



The comparative length of the maxillary and labial palpi, upon 

 which this genus is built, seems to me, in this case especially, to 

 indicate a family rather than a genus. The labrum, however, is 

 of a different shape from that of most other Cicindelidce. 



Cicindela Linn. 

 nivea. 2. C. aenea niveo-pilosa, labro elytrisque glabris albis. 

 Long. Corp. lin. 7- 

 Habitat in Brasilia. D. Hancock. 



Statura fere C. capensis, sed paulo angustior. Corpus asneum : 

 subtus lateribus, capite thorace pedibusque pilis longis niveis 

 decumbentibus, vestitis. Labrum album glabrum. Elytra 

 glaberrima, punctulatissima, alba : scutello suturaque aeneis, 

 prope basin lineis duabus ; interior! longiori, punctorum im- 



pressorum
