8 COLEOPTERA CHLAMYDAE. 



cle which forms the side of the hump (seen from the side 

 behind), the apex of the hump is finely rugose, sides of ab- 

 domen with a large though not particularly prominent tuber- 

 cle, suture dentate. The brassy color and shape will aid in 

 identifying this, should be placed next unicolor Jac. (type in 

 my collection). 



Clilainys spinicollis nov. sp. Quadrate, cyaneous bronzed, 

 head (antennae ?), sides of the thorax and two spots in front, whole 

 body beneath except parts of meso- and metasternum bright orange- 

 fulvous ; thorax with a six spined hump (three on each side) and each 

 elytra with about twelve strong spinous tubercles, suture dentate, pro- 

 sternum very narrow in front and becoming carinate behind, almost 

 tuberculiform in front when looked at from side ; length 4^ mm. 



Type. — One 9 ; Jatahy, Goyaz Prov., Brazil. 



Head finely punctate, with a small mark at the vertex, an- 

 tennae with 2d joint short, 3d a trifle longer, cylindrical, 

 4th and 5th transverse (rest missing), thorax finely and 

 closely punctulate, hump divided by a deep wide median 

 sulcus obsolete in front, and each side divided again trans- 

 versely, the effect being three tubercles on each side, of 

 which the two along the middle are much the stronger and 

 form obtuse spines, the hump proper is green bronze, and 

 this color is continued by the median sulcus and an arm on 

 either side to the anterior margin, forming two triangular 

 fulvous spots in front ; the punctuation of the elytral intervals 

 is coarse and rather regular, finer behind, each elytra has the 

 following tubercles : a strong basal sutural, a smaller imme- 

 diately behind, a large basal median, a small double humeral, 

 a strong transverse lateral median and about seven scattered 

 equally between the middle and apex, the apical sutural being 

 perhaps the most prominent, the two basal and the transverse 

 are the most marked, pygidium thickly finely and somewhat 

 strongly punctate with a smooth median line ; body beneath 

 thickly, legs more finely and sparsely punctate. 



The color and spiny appearance easily separate this form, 

 which I place near spinosa Koll. 



Clilamys g-oyazensis nov. sp. Quadrate cylindrical, dull brown, 

 thorax with a strong raised hump covered with tuberous asperities, 

 sulcus almost entire, deep, smooth and widening in front from about
