ZOROTYPUS SWEZEYI, A NEW SPECIES OF THE 

 ORDER ZORAPTERA FROM HAWAII 



BY A. N. CAUDELL 

 Bureau of Entomology, U. S. Department of Agriculture, Washington, D. C. 



The species of Zorotypus herein descril^ed is based on speci- 

 mens received from Hawaii by Mr. Hebard, of Philadelphia, 

 who kindly submitted them to the writer for determination. 

 Considering the paucity of indigenous forms of Hawaiian in- 

 sects, it seems doubtful if this is a native species. It was natur- 

 ally surmised that this would prove to be an introduced species 

 and probably a described form, more likely one of the East 

 Indian species erected by Silvestri. It is still very probable 

 that this may indeed be an introduction into Hawaii, but a 

 careful comparison with descriptions and figures of the known 

 forms of the genus shows it to differ from them all. It is thus 

 herein described as new, and the specific name swezeyi proposed 

 for it in honor of the collector of the specimens; this name is 

 also suggestive of the supposed habitat, Mr. Swezey having 

 been so intimately associated for many years with Hawaiian 

 Entomology. 



The subecjual second and third segments of the antenna will 

 at once differentiate this new species from the Old World forms 

 and from the Nearctic species snyden, while the more strongly 

 armed ventral margin of the posterior femora will readily separ- 

 ate if from huhhardi. No specimens of Z. neotropicus are avail- 

 able for comparison, l)ut these Hawaiian specimens do not appear 

 to agree with the description of that species sufficiently well to 

 warrant considering them as belonging there. The ventral 

 armature of the posterior femora of neotropicus is apparently 

 less robust than in the species here described and the antennae 

 are also somewhat different. Direct comparison of specimens 

 of both species would probably show various features of 

 morphological dissimilarity.
