is very similar to small eastern specimens collected in North Carolina; 

 many examples of this sort were noted and made limitation of the 

 species difficult. Individual colonies of Eucanthus lazarus appeared 

 to exhibit remarkable uniformity, but considerably more material 

 with exact data is needed to determine if the variation is intraspeciiic 

 or interspecific. 



I was unable to locate the Fabrician type of lazarus, which ap- 

 parently has been lost. However, specimens were compared with the 

 Fabrician specimens bearing the name meliboeus in the collection of 

 the Hope Department, Oxford University Museum, by Dr. F. I. van 

 Emden. The Fabrician specimen, a female in the Hope Collection, 

 bears a label "Lee's Cabinet" and a label afiixed by Dr. Taylor 

 stating, "This may be the type, but I cannot be certain." In case 

 other specimens of melihoeus were in Lee's collection and should be 

 discovered, and in order to avoid possible confusion, the female speci- 

 men bearing the above-mentioned labels in the Hope Department, 

 Oxford University Museum, is here designated as the type of Eucanthus 

 melihoeus. 



Several of my specimens were compared with the type by Dr. van 

 Emden, and a female from Havana, lU., was picked by him as very 

 similar to the type, differing mainly by being slightly larger and lighter 

 in color. The type, while being rather dark, has the large antennal 

 club of the northern and midwestern lazarus. Because of Dr. van 

 Emden's careful notes I am fairly certain that melihoeus Fabricius is 

 identical with lazarus as described above. 



"While Eucanthus lazarus is the most common and wide-ranging 

 species of the Bolboceratini, little has been published on its biology. 

 Brown (1927, p. 27) mentioned that the species was often collected 

 in the same pasture or old roads where he would find Bolhocerosoma. 

 Wallis (1928, p. 112) mentioned that Sim found the species burrowing 

 in the same areas, old roads and golf courses, where he took Bolhoceras. 



All available biological information was summarized and the larva 

 of Eucanthus described for the first time by Ritcher (1947, pp. 10, 11). 

 He stated that the larvae he described were collected in the soil of 

 a vineyard near Fayetteville, Ark., by M. W. Sanderson in the summer 

 of 1942. Unfortunately, there was no additional information. 



Since Ritcher's work, nothing has been added to increase the infor- 

 mation on the habits of lazarus lazarus. The species occurs rather 

 sparingly in the mountain and piedmont regions of North Carolina, 

 but in more northern and western states it is locally common and 

 appears frequently in some of the collections from midwestern states. 



The species has often been recorded as attracted to light. I col- 

 lected a number of specimens in a light trap at Oxford, N. C, on 

 Aug. 2, 1951, and again on August 10. A few specimens were found
