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 exemplified. This is the small group of Erycince. Here the anterior 

 feet are spurious in the male, 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 the 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 Erycince, 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 

 Hesperidce, the continent of America has hitherto afforded 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 of Erycina 

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

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

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

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

 unstreitig, zu dem merckwilrdigsten das in der Entomologie angetrqffen werden kann." 



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

 references to the illustrations of the metamorphosis and perfect insect of the Vermifotm 

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

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