 Pseudophasma cryptochlore ^^ n. sp. 



Type. — c? ; San Carlos, Costa Rica. (Schild and Burgdorf.) [Cat. 

 No.V,349, U. S. N. M.] 



Apparently closely allied to P. gambrisius (Westwood),^^ from Vene- 

 zuela, but differing in the structure of the apex of the abdomen, the 

 shorter mesonotum and quite different coloration. Relationship also 

 exists with prasinum (Serville) and pholcus (Westwood). 



Size small; form slender. Head slightly longitudinal, subequal, 

 considerably wider than the pronotum ; occiput with several fine longi- 

 tudinal lines; ocelli very distinct, the anterior one considerably in 

 advance of the others; ej'es subglobose, very prominent; antennae 

 equal to the body in length, first and second joint cylindrical, the latter 

 considerably smaller and shorter than the basal joint, third joint equal 

 to the fourth and fifth together. Pronotum about two-thirds the length 

 of the mesonotum; anterior and posterior margins subtruncate; cruci- 

 form impression slight, the transverse arm toward the lateral margins 

 deflected posteriorly; anterior angles normal though spiraculiferous. 

 ]\Iesonotum rather short and slender, slightly and evenly constricted 

 toward the middle; surface sparsely granulate; median longitudinal 

 sulcus slight but distinct ; mesosternum rugulose with a distinct, though 

 somewhat irregular, median carina. IMetathorax al)out equal to the 

 prothorax and mesothorax in length, beneath with a slight median 

 sulcus. Tegmina not more than half the leng-th of the metathorax, 

 ovate ; median tubercle low and somewhat elongate ; longitudinal veins 

 rather regularly disposed, transverse A'eins irregularly placed and pro- 

 ducing a reticulate effect. Wings almost equal to the body in 

 length, twice as long as broad; costal area with the transverse veins 

 rather regularly disposed. Abdomen with the six basal segments 

 longitudinal, very gradually decreasing in size toward the apex; sev- 

 enth and eighth segments subequal in length, each shorter than the sixth ; 

 ninth segment rather shorter than the eighth, apically subtruncate ; cerci 

 rather short, terete, slightly curved; subgenital opercule slightly ex- 

 ceeding the apex of the eighth dorsal segment, cj^mbiform, the margin 

 rounded, but de^'eloped into a distinct lip or rim. Limbs of moderate 

 length, the anterior and median femora consideral^ly exceeding their 

 respective tibiip in length. Anterior femora equal to the pronotum, 



*^ Kpv-ro^j hidden, and ;i'/w/)oc, green, in allusion to the green of the ventral 

 surface.
