15 — Crest of the thoracic process abrupt and well defined by a continuous ele- 

 vated margin; larger species, the posterior fascia small, irregular and very 

 near the apex calcaratus Horn 



Crest sribobsolete, represented only by a few detached asperate points; posterior 

 fascia at apical fifth ; elytra with erect sette ; small sjiecies. 



delicatus Csy. 



Crest completely obsolete, the posterior fascia large and enveloping the apices; 

 median fascia greatly prolonged along the suture, becoming bifurcate; 

 elytra without erect setae planicoriiis Laf. 



The characters of planicornis, which is the only species not 

 before me, are taken from the figure given by LaFerte; this figure 

 does not, however, at all agree with the description, which states 

 that there is a small scutellar spot, a median sinuous fascia and 

 another ante-apical, which is composed of two lunules ; this would 

 make the markings agree nearly with those of delicatus, but as the 

 description states that there are no " polls raides " in planicornis, 

 and as these ai'e very evident in delicatus, I prefer to regard 

 the two species as distinct for the present. As I have before 

 explained (Bull. Cal. Acad. Sci., I, p. 333), delicatus is in no way 

 closely related to monodon or jnlatei. 



I have considered pilatei and decoloratus of LaFerte as varities 

 of monodon for the present, as I have not been able to identify 

 them, but it is more than possible that they represent valid species. 



The genus having been so recently reviewed by Dr. Horn (Tr. 

 Am. Ent. Soc.,XI, 1884, p. 165), it is only necessary at the present 

 time to describe the species announced as new in the above table. 



X. Ibalteatiis. — Moderately stout and shining, rufo-piceous, the elytra 

 black with a broad and even transverse fascia at basal third, and another, 

 equally straight and transverse but narrower, at apical third ; basal margin 

 and apex also paler; vestiture very fine, short, even and only moderately close 

 anteriorly, coarser and denser on the elytra, where it is pale cinereous on the 

 pale bands, elsewhere brownish, without erect setae. Head distinctly smaller 

 than the prothorax, the eyes rather large, slightly longer than the tempora; 

 antennas distinctly longer than the head and prothorax, stout toward apex, 

 the tenth joint but slightly longer than wide. Prothorax slightly transverse, 

 subglobular, finely, closely punctate, the horn well developed, two-thirds 

 longer than wide, very feebly narrowed at base, not dentellate, the crest 

 strongly developed and surrounded by a fine elevated and non-dentellate 

 border. Elytra three-fourtlis wider than the prothorax, evidently less than 

 twice as long as wide, feebly dilated behind; disk very minutely, evenly, 

 moderately closely punctate; humeral Impression feeble; post-scutellar depres- 

 sion distinct. Under surface miniitely and closely punctate, the legs moder- 

 ately slender, testaceous. Length 110 mm. ; width 1.0 mm.
