THE MTRIAPODA OF NORTH AMERICA. 



Greenish-brown, with three longitudinal stripes of deep green ; head anteriorly shortly pilose, impressed 

 with a median longitudinal line, and in front of the eyes a curved one on each side, and another transverse 

 between the eyes; a-ntennas and mandibles ferruginous; scuta roughened with numerous spines, strongly 

 imbricate, with the angles rounded, the margins elevated but thin, and the spines more pronounced than 

 in C. coleoptrata; sides generally tinged with rufous; femora each with a single deep green ring; tibiae and 

 tarsi biannulate ; last pair of feet in the male scarcely \ longer than the body (in female twice longer) ; first 

 metatarsal joint nearly four times as long as the second, about equalling the five following conjoined ; ventral 

 surface yellowish; sterna medianly canaliculate.

In specimens preserved for some time in alcohol, all traces of the original color are lost, 

 the whole animal turning to a testaceous hue. The coloration of a very large fresh female 

 before me is as follows : 



The general tint is a very light olive-brown ; the median stripe is black, continuous, 

 strongly defined, and extending from between the eyes to the posterior border of the 

 penultimate scutum, where it abruptly terminates. The lateral stripes are black, strongly 

 defined, interrupted, and extending from the eyes to the posterior border of the last 

 scutum. The interruptions are so arranged that most of the scuta present three blotches 

 on each side. The anterior portion of the head has two stripes converging anteriorly to 

 the median line. In front of these there is a sub-round marking prolonged anteriorly. 

 Most of the femora are provided with a very incomplete greenish black annulus, which is, 

 however, complete on the last pair. The tibia and tarsi are biannulatcd. The dorsal sto- 

 mata are bordered with brilliant white. 



Authorities differ as to the validity of this species. I have never seen G. coleoptrata, 

 and therefore cannot offer an opinion.
