Androl.y perns. 



Tibise with spurs ou the middle and posterior legs; anterior coxje sepa- 

 rated by a thiu lamina Malacorhiiiiis. 



7. — Protborax narrowed at base; all the tibipe with spurs; sexes unlike in form 



(MetacycUtes) Metacycla. 



Prothorax not narrowed at base; all the tibise with spurs; sexes similar 



(Agelasticites) Malacosoiiia. 



Prothorax not narrowed at base; tibite without spurs; sexes similar in form, 

 but with differing antenufe, either in form or number of joints

mylites) Agelasa. 



MOIVOCESTA Clark. 



Antennse slightly thickened, a little longer than half the body, 

 joints 1-3-4 about equal in length, third about half, joints 5-10 

 gradually shorter, eleventh about as long as the seventh. Head de- 

 flexed, moderately deeply inserted, eyes oval, entire ; clypeus trun- 

 cate, abruptly thickened behind the margin, labrum large, subacutely 

 oval in front; maxillary palpi not very robust, the terminal joint 

 acute, as long as the preceding joint and more slender; mandibles 

 stout. Thorax short and broad, transversely depressed ; scutellum 

 moderately large, the apex oval ; elytra somewhat inflated, broader 

 behind, the epipleurse very narrow, extending three-fourths to apex ; 

 prosternum not extending between the coxa?; metapleurjB moderately 

 wide, narrower posteriorly. Legs not long ; tibiae slightly broad- 

 ened at tip, the outer edge grooved, apex without spurs ; tarsi rather 

 broad in both sexes, claws bifid. 



This genus contains species formerly placed in Ccelomera, from 

 which it differs by characters of somewhat doubtful value. The 

 species are numerous, and for the most part Brazilian, a number are 

 found in Mexico, but one occurs in our regions. Chapuis placed the 

 genus in a group, Coelomerites, which may readily be distinguished 

 from all others with entire anterior coxal cavities and bifid claws by 

 the deeply grooved outer edge of the tibise.
