88 PHYTOPHAGA. 



The elytra of this species are devoid of the usual protuberances, but have three 

 tubercles, of which one is placed at the middle, the others near the sutural and lateral 

 margins towards the apex. The general colour is a brilliant blue. 



39. Chlamys mixta.

 Eab. Mexico, Merida \ Yucatan ; Nicaeagua, Chontales (Janson). 



The type of this species has a rufous head and the thorax spotted with the same 

 colour. I possess a specimen from Nicaragua which, with the exception of the rufous 

 tarsi and base of the antennae, is entirely black, and, although differing somewhat in 

 sculpturing from the type, yet not to such a degree* as to necessitate considering it a 

 different species, although the thorax in my specimen is more transversely reticulate 

 instead of rugose, and the edges of its elevation are more sharply defined ; but, as it 

 does not differ materially in other respects, I must regard it as a variety, unless more 

 specimens should prove the reverse. 



40. Chlamys signaticollis. 



Chlamys signaticollis, Lacord. Mon. p. 839 1 . 



Eab. Mexico \ — Colombia \ 



A species principally distinguished by the sculpture of the thorax, which consists of 

 longitudinal ridges. 



41. Chlamys venusta. 



Chlamys venusta, Lacord. Mon. p. 781 \ 

 Eab. Mexico, Oaxaca K 



This species is principally distinguished by the colour of the thorax and the isolated 

 tubercles of the elytra. 



42. Chlamys pardalis. (Tab. IV. fig. 25.) 



Chlamys par dalis, Lacord. Mon. p. 782 \ 

 Eab. Mexico \ San Andres, Tuxtla (Salle). 



This is one of the most easy recognizable species amongst the whole of the Chlamydee, 

 on account of the spotted upper surface. Two specimens from M. Salle's collection are 

 before me— one a female from San Andres, which is figured here, the other a male, 

 which does not materially differ, but is a little smaller and devoid of the abdominal 

 fovea.
