Hah. — Cajabon, Guatemala (F. C. Sarg). 



Two specimens found by my colleague, Mr. Oldfield 

 Thomas, on a bat, Molossiis ahrasus, Temminck. 



The discovery of this species throws some light on the 

 affinity of these insects, as I notice that in these fresh 

 specimens the parts which in my former paper I called 

 the dorsal plates of the mesothorax, as they did not 

 seem to be separated from it, are distinctly separated, 

 and appear quite like elytra. With the point of a 

 fine needle I was quite able to lift them up at the apex, 

 but they are soldered together at the suture. Under 

 these circumstances my former opinion that these insects 

 should be placed near the Hipj^ohoscidfe is, I think, quite 

 proved to be incorrect ; in which case Professor West- 

 wood's view of their affinity with the Hemiptera seems 

 to be the only alternative. 



The tarsi in the species now described are four-jointed. 

 P. Jumarins has four joints, as has also one sex of 

 P. molossus ; the other sex of P. molossus is represented 

 as having only three joints. I believe P. lyrce and 

 P. sp)asmce have four joints, but the apparent division 

 between the 3rd and 4th joints is so obscure as to leave 

 room for doubt on this point.
