THE CANADIAN ENTOMOLOGIST. 145 COLLECTING NOTES ON COLKOPTERA. BY W. KNAUS, MCPHERSON, KANSAS. While collecting at Brownwood, Texas, in the latter part of May, 1904, I secured half a dozen three-and four-inch sections of a Mesquite tree, about three inches in diameter, that had been cleared from land the preceding fall. The sections were infested with Coleopterous larvae, and were put into a breeding box to see what would develop. The first trans-formation into imagoes was in July, when a small Ptinid, Trogoxyloii Cali/ornicum, Lee, began to emerge in numbers. A little later three or four specimens of a small Cucujid, Lathropus vei'fialis, Lee, emerged. In August a dozen specimens of Sinoxylon Texaniun, Horn, had trans-formed, their cells being in the white wood part of the Mesquite. After emergence, a number of these bored holes straight into the wood their full length, or deeper. At this time also appeared three or four Clerids, Elasmocerus ter??ii?ialis, Say, pupating like the Sinoxylon, in the white wood near the bark. August 4 the first specimen of Cyllene crinicornis^ Chev., emerged ; two or three September 18, and two or three others the first week in October. About fifty per cent, of the larvae of this species died before entering the pupal state. The larvae channelled through all parts of the wood. Two or three parasitic Hymenoptera emerged up to November. The Trogoxylon continued to thrive and transform until extreme cold weather. Examinations of the wood in April and May, 1905, showed the Trogoxylon still at work in the white wood, and every exam-ination during the summer and fall showed live and dead insects of this species. Some time during July four more specimens of the Longicorn, Cylletie cri7iicorjiis, transformed, and were found dead, and two or three dead Si7ioxylon Texaman and one Elas)iiocerus ierminatus. Say, were also found. The capture of two or three specimens of Hilipus squa7?iostis, Lee, on spice wood near Galena, Kansas, by Mr. Eb. Crum, has been recorded. This fine Curculionid was described from specimens taken from under pine bark in Georgia. It has also been taken in Kentucky, but it is rather unexpected to find the species in Kansas. Dr. G. H. Horn, in his " Halticini," 1887, describes Crepidodera longula, and says : " Collected at McPherson, Kansas, on Willows, by William Knaus." The Doctor was slightly in error. The type specimen was collected near Osage City, in June, 1883, ^Y myself, and occurs from May, 1906
