The genus Ectecoiis is entirely tropical American in its distribution, 

 and its representatives may be recognized by reference to the synoptic 

 key given on a preceding page.

 belong here or at least near to it. Tt bears the label "Muhez Freire,

This genus, like several of the other genera of the family, is entirely 

 tropical American in its distribution. The representatives undoubt- 

 edly live largely among rocks in the crevices of and beneath which 

 they find safe retreats from the many natural enemies they must have. 

 Caves are also known to afford them suitable retreats. Only a single 

 representative is at hand in the following apparently undescribed 

 specie?. 



55. Dyscophogryllus castaneus sp. nov. 



A medium-sized, glabrous (cf) or pubescent (9) reddish brown 

 insect, in which the male is provided with well-developed tegmina, 

 while the female is entirely apterous. About the size of D. ontho- 

 phagiis Berg of Uruguay. 



Head short, rounded, a little narrower than the apex of the pro- 

 notum, the occiput smoothly and evenly rounded, the eyes fairly 

 large and somewhat prominent, the rostrum short, broader than the 

 diameter of the basal antennal segments, ocelli large; the maxillary 

 palpi pale, elongate, the apical segment somewhat expanded and 

 arcuate. Pronotum formed as in members of allied genera, a little 

 wider than long, the anterior edge very shallowly and broadly roundly 

 emarginate, behind straight. Tegmina of male well developed, cover- 

 ing about two-thirds of the abdomen and well provided with veins. 

 Front and middle legs moderately long, the anterior tibi;c with their
