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
