SOME INVERTEBRATA FROM ST. KILDA 87 



MYRIAPODA. 



Two Chilopods, both common and widely-spread species, were 

 collected, namely : 



Lithobius forficatus (Linn.), and 



Geophilus carpophagus, Leach. A few of each. The only 

 representative of the Diplopods is 



lulus britannicus, Verh. Three specimens, agreeing precisely 

 with others I have from the coasts of East Lothian and Fife. 



The following Insects are in the collection. 



INSECTA. 



COLLEMBOLA AND THYSANURA. 



Tomocerns tridentifer (Tullb.). A few. 



Entomobrya albocincta (Tempi.). One example; but Mr. 

 AVaterston says it was common. 



E. nicoktii (Lubb.). One. 



These three Springtails are all common and generally distributed 

 in the British Isles. 



Machilis maritima (Leach). Several. As might be expected, 

 this Bristle-tail is abundant on St. Kilda, occurring, Mr. Waterston 

 tells me, not only at or near high-water mark, but even in the stone 



walls about the village. 



ORTHOPTERA. 



Forfiada auricularia, L. The Earwig is common on St. Kilda, 

 whence it has already been recorded by Mr. C. W. Dale ("Entomo- 

 logist," January 1889). 



MALLOPHAGA AND PSOCID^E. 



Lipeunis stapliylinoides, Denny. A number of both sexes from 

 the Gannet. The males are certainly this insect, and I have no 

 doubt so also are the females, though they bear a close resemblance 

 to Denny's figure of his Docophorus bassance. There is also an 

 example of a quite different Lipeurus from a gannet fiddle- shaped 

 head and narrower body which neither Denny's " Monograph " 

 nor Giebel's " Insecta Epizoa " enables me to identify. 



Clothilla pnlsatoria (L.) One specimen. I have found this 

 little Psocid commonly in houses and other buildings in various 

 parts of Scotland. 



ANOPLURA AND COCCID/E. 



Pediculus capitis, Nitz. One example. 



Orthezia cataphracta (Shaw). One. Common throughout 

 Scotland, and already recorded from St. Kilda in Newstead's
