PARADISE KEY — SAEFOKD. 399 



This species has an almost straight, slender snout, and its antennae 

 are not elbowed like those of the Rynchophorus, but moniliform, 

 like a necklace composed of many beads. Its life history has not been 

 studied, but in a closely allied genus the females puncture the bark 

 of an oak and deposit their eggs. The larva, a cylindrical grub, with 

 three pairs of legs and an anal prop leg, bores into the solid wood. 



Other Coleoptera collected in the park are a predatory tiger beetle, 

 Cicindela tortuosa, dark colored above and metallic beneath ; a water 

 scavenger, Philhydrus nebulosus ; a large click beetle, Alaus oculatus, 

 which has the habit of springing up suddenly when laid down on its 

 back ; Bupreslis lineata, whose grubs are known as hammer-heads or 

 flat-headed borers; Calopteron reticulatum, with broad yellow and 

 black bands; several lamellicorns (Scarabaeidae), including Phileu- 

 rus truncatus, Phileurus valgus, the yellowish brown vine chafer, 

 Pelidnota punctata; Anomala margmata Fabr., which, like the pre- 

 ceding, feeds on the leaves of wild grapes; the handsome, green 

 Euphoria Umbalis; and Trichius delta, easily distinguished by a 

 delta-shaped spot on its back; several longicorns (Cerambycidae), 

 including the twig girdler, Oncideres cingulaia, the gumbolimbo 

 borer, Mallodon dasystomus (determined by F. C. Craighead), and 

 the very rare Euryscelis suturalis. 



In addition to the above-mentioned species the collection includes 

 several small leaf beetles (Chrysomelidae), several weevils infesting 

 palmetto seeds, Calandrids injurious to maize and other grasses ; and 

 a number of minute bark beetles (Xyleborus spp.) belonging to the 

 Scolytidse, which have been described by Dr. Andrew D. Hopkins 

 of the Office of Forest Insects. To speak of them in detail is beyond 

 the scope of the present paper. 



MOTHS AND BUTTERFLIES. 



The most attractive insects of the Roj^al Palm State Park are un- 

 doubtedly the Lepidoptera. For the identification of those in his 

 collection the writer is indebted to Dr. H. G. Dyar and Mr. Carl 

 Heinrich, of the Bureau of Entomology. The order to which they 

 belong takes its name, Lepidoptera, from the minute scales which 

 cover the wings and give them their varied and beautiful color 

 patterns. On plate 26 is shown one of these scales from the wing 

 of a Papilio, or swallowtail butterfly, magnified 750 diameters; and 

 on figure 21 the arrangement of these scales on a butterfly's wing, 

 overlapping one another like shingles or tiles. 



MOTHS. 



The rarest and most interesting moth collected on Paradise Key 

 is the West Indian Perigonia lusca interrupta Walker (pi. 47, fig. 1),
