144 Mr. G. C. Champion's Revision of the 



Chihuahua and Guanajuato respectively) having been seen 

 by me. Hoge has sent a long series of the other forms 

 from Tacambaro, Michoacan. The prothorax has three 

 transversely placed spots, or a trapezoidal patch, on the 

 disc in all of them. The femora are sometimes red at the 

 base. 



11. Chauliognathus lecontei, n. sp. 



Chauliognathus profundus, Crotch, Trans. Am. Ent. Soc. v, 

 p. 78 ; Lee, Trans. Am. Ent. Soc. ix, p. 43 (nee Proc. 

 Acad. Phil. 1858, p. 71); Gorh., Biol. Centr.-Am.,

Rufous, the palpi, two elongate streaks on the disc of the pro- 

 thorax (sometimes reduced to two small spots or altogether wanting), 

 the apex of the elytra broadly, the apex of the abdomen, and the 

 legs (the base of the femora sometimes excepted) black, the antennae 

 (as in C. profundus) usually with joints 3-11 in part testaceous, and 

 for the rest black. 



Length (excl. head) 12^-14 mm. ((^ ?.) 



cj. Aedeagus : median lobe stout, strongly curved, produced at 

 the apex into a long spoon-shaped process; left lateral lobe long, 

 abruptly angulate at about the middle, the basal portion oblong, 

 spoon-shaped, the apical portion much narrower and strongly 

 hooked at the tip ; right lateral lobe much shorter than the left, 

 compressed, obliquely bent outward from about the middle, the 

 tip rounded. Plate V, figs. 14, 14a. 



Hab. North America, Arizona; Mexico, Chihuahua. 



The above description is taken from a long series sent 

 by Hoge from Chihuahua city and various examples re- 

 ceived from Morrison as from Sonora. There is no variation 

 in the colour of the elytra, but the two elongate streaks 

 on the prothorax are sometimes reduced to small spots 

 or are altogether wanting. C. lecontei is smaller and 

 redder than C. profundus, the head is not black as in that 

 species, and the abdomen (except the aedeagal cap of the 

 male and the tip to a greater or less extent in the female) 

 is almost wholly red. The aedeagus of the male does not 

 differ greatly from that of its near ally. Mr. Wickham 

 [Bull. Lab. Iowa, ii, p. 342, pi. 60, fig. 17 (1893)] has 

 described the metamorphoses of the present insect at some 

 length.
