ON A COLLECTION OF MYRIAPODS FROM 

 COSTA RICA 



BY RALPH V. CHAMBERLIN 



i^^^ Cambridge, Massachusetts 



These notes are based upon a small but very interesting col- 

 lection of chilopods and diplopods made by Dr. Philip P. Calvert 

 in Costa Rica during 1909-1910. Fifteen species are represented, 

 of which seven appear to be new. The collection will be placed 

 in the Academy of Natural Sciences of Philadelphia, with some 

 duplicates in the Museum of Comparative Zoology at Cambridge, 

 Massachusetts. 



The following species were taken from among the leaves of 

 members of the BromeUaceae: 

 Chilopods 

 Otocryptops melanostomus (Newport) 

 Newporlia longitarsis (Newport) 

 Scolopendra viridis (Say) 



Diplopods , ^ ■ 



Aphelidesmus calverti sp. no v. 

 Aphelidesmus sp. 

 The crowded expanded bases of the leaves of the bromeliads 

 accumulate dust and humus and catch and retain a considerable 

 amount of moisture, so that they would seem naturally to furnish 

 favorable retreats for myriapods. A larger list of myriapods 

 found inhabiting these plants is given by Picado,^ and there seems 

 no reason to doubt that the list may in time be extended to include 

 a large proportion of the myriapod fauna of the region. I am 

 under obligation to Dr. Calvert for the privilege of studying this 

 material. 



CLASS CHILOPODA 



SCOLOPENDROIDEA 

 CRYPTOPIDAE 

 Cryptops sp. 



A single specimen from Juan Viiias (June 23 to 29, 1910). The 

 anal legs are missing, making accurate determination of the species 

 difficult.
