46 BULLETIN 18 2, UNITED STATES NATIONAL MUSEUM 



quadrate ; width to length as 3 to 2% ; midline finely and evenly im- 

 pressed, impunctate ; lateral sulci feeble, not exceeding one-third the 

 length of pronotum; sparsely, finely, and very irregularly punctate; 

 confusedly strigulose, more regularly at sides. Elytra with striae 

 moderately punctate ; intervals finely irregularly punctate ; sixth stria 

 marked by a short impressed line at basal third and scattered punc- 

 tures posteriorly. Length, 7 mm. 



Type locality. — Guadeloupe, Pointe-a-Pitre. 



Types. — One example in the British Museum from the Chevrolat 

 collection. Collected by F. de L'Herminier. 



Records. — The following are the records known to me : 



[Hispaniola: Haiti (Leng and Mutchler, 1914).] 



Guadeloupe: (Erichson, 1840; Fauvel, 18G5 ; Fleutiaux and Salle. 1889; Leng 

 and Mutchler, 1914; British Museum). 



jSpeciniens examined. — Three examples of this species were studied 

 in the British Museum, and one of these was afterward borrowed 

 for further study. 



Remarks. — This species has apparently been collected only once, 

 probably at the same time as P. capricornis. If this is so, then the 

 remarks under capricornis apply equally here, and this also must be 

 regarded as a doubtful West Indian record. The record of Haiti 

 by Leng and Mutchler is unsupported by any specimens or data 

 known to me and is distinctly to be questioned. 



Nothing has been recorded concerning the habits of this species.
