Mandihles obliquely truncate at apex, the ti-uiication feebly, un- 

 equally, obtusely bilobed ; elytra strongly dehiscent in apical 

 third to half, the punctured series distinct throughout the width ; 

 genital armature sinuato-truncate and completely non-lobed in 



the male Andriniiis 



Legs long and slender, the tarsi as long as the tibije ; body more 

 longitudinally convex ; mandibles deeply notched at apex, the 

 lobes acute and subequal ; elytra dehiscent in more than apical 

 third, deeply striato-sulcate throughout the width ; genital arma- 

 ture deeply bilobed in the male, the lobes very prominent. 



Capnochroa 

 Anterior tarsi not dilated in the male, but usually strongly compressed 

 and distorted ; body generally strongly, longitudinally convex. 

 Mandibles distinctly notched at apex, the apices acute and subequal ; 



antennae more or less compressed and serrate Cistela 



Mandibles very oblique and feebly notched at apex, the upper lobe 

 much longer and broader than the lower, acute ; antennae long and 

 filiform Alldrocliil'lIS 



XYSTROPLS Sol. 

 Prostenus Horn nee Latr. 



The head in Xystvopus is almost of the same form as in Helops 

 and some other allied genera of Tenebrionidse ; in Stenoehidus it is 

 of a more strictly eistelide type, but still the general form of body 

 recalls the Tenebrionidre much more forcibly than any of the typi- 

 cally eistelide genera which follow. In fact there seems to be some 

 decided coordination between the form of the abdominal process 

 and relationship with the Tenebrionida\ This is my reason there- 

 fore for placing Xystropus and its allies first instead of last in the 

 series. 



In Xystropus as represented by califorvicus, the eyes are small, 

 short and strongly transverse, the antenna? moderate in length, 

 stout, incrassate and compressed, the maxillary palpi moderate, with 

 the apex of the fourth joint but moderately oblique and the angle 

 at the base much less than right, resembling somewhat that of 

 Helops californicus. The prosternal process is horizontal poste- 

 riorly, then abruptly vertical to the level of the prosternal side- 

 pieces, where it becomes strongly dilated, widely separating the 

 latter at the posterior margin ; the hind coxae are distinctly sepa- 

 rated by a rounded abdominal projection. The legs are short, the 

 tarsi without lobes, clothed beneath with long coarse hair, and with 

 the basal joint of the posterior unusually short. The ungues are
