52 INTRODUCTION. 



on the anterior feet cannot with propriety be omitted. These are again perfect, 



being provided with five tarsi, and with claws as in the Vermiform and Juliform 



stirpes. But there exists, at the confines of the Thysanuriform and Anopluriform 



stirpes, an intermediate group, by which the transition from one stirps to the other is 



most strikingly exempUfied. This is the small group of Erycince. Here the anterior 



feet are spurious hi tlieviale, and perfect in the female. For an illustration of this most 



remarkable structure I refer the reader to pi. 11, where in fig. 3, the details of both 



sexes are exhibited in the dissection ; fig. 3, e and f, exhibit tlie spurious feet of the 



male, and fig. 3, g, the perfect feet of the female ; and the lateral view of the 



perfect insect, fig. 3, a, shows the relative proportion and situation of the spurious 



feet in the male, in a very striking manner. I consider it a fortunate circumstance 



that my Eastern collection has enabled me to illustrate this point, and to show in a 



satisfactory manner, the union of the two stirpes ; for the true region, not only of the 



group of Erycinoi, but of the whole Anopluriform stirps, is the New "World. While 



I have discovered in Java three species of Erycince and about thirty-five species of 



Hesperid(X, the continent of America has hitherto afiforded at least one hundred 



species of the former, and an innumerable host of the latter. The details regarding 



the Erycince, as observed in Java, will be given in their proper place in the work, but 



I shall add in this place that the metamorphosis of this group, as far as it is yet known, 



confirms the station assigned to it ; and the figure of the larva and chrysalis oi Erycina 



Midas, from the sixth plate of the continuation of Cramer, by StoU, gives an 



interest to the diagram, which I trust will meet with approbation. I shall only 



transcribe the remark of Hoffinansegg on this group, contained in his remarks on 



the Erycina Oppelii, in "Wied. Zool. Magaz. T. i. No. 2, p. 95. " Erycina geKort 



unstreitig, zu dem merckwUrdigsten das in der Entomologie angetroffen moerden kann" 



I shall conclude these introductory remarks, with a recapitulation of the various 

 references to the illustrations of the metamorphosis and perfect inject qf the Vermiform 

 and Chilognathiform or Julform stirpes, given on the plates belonging to the first 

 part, in order to exhibit them in a connected point of view.
