carinae prominent, at their upper extremity somewhat sinuous, from 

 a point opposite the median ocellus evenly divergent to the lower 

 corners of the face. Antennae filiform, a little longer than the head 

 and pronotum taken together. Pronotum rather strongly rugoso- 

 punctate, much more closely so on the hind lobe, the dorsum gently 

 tectate, viewed in profile a trifle arcuate; median carina fairly coarse 

 and prominent, distinctly severed by all three transverse sulci, the 

 posterior one plainly in advance of the middle; anterior margin 

 roundly advanced at middle upon the occiput, hind margin widely 

 angulate; the sides of hind lobe decidedly divergent, giving the 

 insect a robust appearance about the thorax. Meso- and meta-thorax 

 moderately enlarged and rather closely and profoundly rugoso- 

 punctulate. Tegmina large, long, for the most part membranous, 

 rather sparsely veined on outer two-thirds, a little more closely so on 

 the basal portion. Legs about normal, the hind femora not especially 

 robust at base, but with coarse apical portion and heavy tibiae, spines 

 of the latter heavy, rather strongly curved and for the most part 

 pallid, the upper carina of the femora rather prominently serrate. 

 Prosternal spine slender, erect, as long as the coxal joints of anterior 

 legs, the apex rounded. 



Length of body, 9 , 60 mm., of pronotum, 15 mm., of tegmina, 

 71 mm., of hind femora, 33 mm., of antennae, 19 mm., greatest width 

 of pronotum, 12 mm. 



Habitat. — This magnificent locust bears the label " Mathewtown, 

 Great Inagua I., Bahamas, February 23, 1909, Worthington." The 

 type is the property of the Carnegie Museum. 



This is by far the largest species of the genus, if not the most beauti- 

 ful, and must be a very attractive insect when alive. How it has thus 

 far escaped collectors is an enigma to the describer. It is not very 

 closely related to any of the other North American forms, nor does it 

 approach those of South America any closer.
