126 ¥TRST ANNUAL BEPOR'f Otf 



O. B. Galusha, who was then with the ad int< rim committee visi 

 Sovitlieru Illinois, sent me a worm in all respects similar which was 

 found boring into the root of an apple tree. I have also received 

 Osage orange roots from Kansas which were being bored by the same 

 fellow, and he is evidently partial to rotten oak stumps lor not only 

 have several persons who are well able to judge, assured me that they 

 have found him in such stumps, but Air. A. Bolter, of Chicago, also found 

 ■it in such stumps in Kentucky, and sent me the specimens (or identi- 

 fication. At the meeting of our State Society, at Columbia, Mr. I. N. 

 Stuart even avowed that he had found it partly grown, not only in seed- 

 ling apples but in the roots of corn stalks, while Chas. Connon, of 

 Webster, assures me that he has found it in the heart of felled hick- 

 ory, and I ascertained that he was perfectly capable of distinguishing 

 it from the common borer (Gerasphorus ductus, Drury), which infests 

 hickory when felled, and which causes what is known as "powder 

 post, 1 ' he being quite familiar with this last named insect. There are 

 several large beetles in the West which must have larvae very similar 

 in appearance to this, and it is not at all unlikely that different insects 

 have here been confounded, but the figure at the head of this article, 

 with the following description of this Grape-Root borer, will enable 

 any one to recognize it in the future. 



Larva of Orthssoma c'i'M.\r>Ricu>;i, (?) F;ibr. — Average length when full grown, 3 inches. 

 Color pale yellowish white, partly translucent, with glaucous and bluish shadings, and a distinct 

 dorsal line of the last color. Segment 1 rather horny, rather longer thaa 2, 3 and 4. together, 

 broadening posteriorly, slightly shargreened and whiter than the rest of the body, with a rust- 

 colored mark anteriorly. Segments 2 and 3 shortest and broadest, the body tapering thence grad- 

 ually to extremity, though there is usually a lateral ridge on segment 12 which dilates it rather 

 more than the segments immediately preceding it. This segment 12 is also the longest, the terminal 

 one being quite small and divided into three nearly equal lobes. A swelled hump crossed with two 

 [Fi"\ fiS.] impressed transverse lines, on segments 4, 5, 6, 7, 8, 9 and 10. Stigmata 



# rust-colored, 9 in number, the first and largest being placed on a fold in 

 the suture between segments 1 and 2. Head brown, verging to black on 

 anterior edge. Mandibles large, strong, black, with one blunt rounded 

 tooth, giving them a somewhat triangular appearance; anntentc 3-jointed 

 and brown, especially at tip; labrum fulvous, fuzzy and with a brown 

 base; maxillary palpi 4-jointed, the basal joint much swollen, the ter« 

 niinal joint brown, and a ring of the same color at sutures of the other 

 joints; labial palpi 3-jointed, the basal joint also swollen, and the ter- 

 minal joint and satures of the others brown. Six rudimentary 2-jointed 

 fuscous Eeet a.- shown at Figure 68. Venter tubercled as on the back, these tubercles being especi- 

 ally prominent on segments 6, 7, S and 9, where they recall prole.gs. The young larva differs only 

 in lacking the rust-colored mark on segment 1. 



Now, to what insect does this borer belong? It is manifestly the 

 larva of some long-horned beetle of the family Peioxid.e, but of what 

 particular species cannot be positively stated till the beetle is reared 

 from grape-root-boring larvae. Before another year shall have passed 

 away, I hope to definitely determine this point, but meanwhile, I have 

 every confidence that it will produce the Cylindrical Orthosoma ( Or-
