the form and undulation of the yellow elftral fasciae, and there is really no structural 

 difference, or any of importance in the punctuation. 



The brown variety with luteous fasciae mentioned by Lacordaire is, I believe, only a 

 less mature example of this species. Fig. 5 is taken from a specimen from Chontales, 

 and fig. 6 from an example of the var. P. distortus from Toxpam.

Hah. Nicaragua (Salle), Chontales (Janson l , Belt) ; Panama, Bugaba, La Caldera in 

 Chiriqui (Champion). — South America, Colombia l . 



A species resembling P. pcecilosomus in the colour and markings of the thorax, but 

 smaller and without the double row of punctures. The single specimen in the Salle 

 collection is very small, 10 millimetres only in length. Apparently but few examples 

 have been sent.
