36 MEMOIRS ON THE COLEOPTERA 



where the thoracic base is somewhat wider than the apex, with 

 notabty large and shallow fovese and the elytra are broadly inflated. 

 Haruspex may be the Vancouver form mistaken for quadrifoveo- 

 latum Mann., of the Island of Sitka; the latter is however a very 

 much smaller and narrower species, 3.3 by 1.3 mm. in dimensions; 

 the upper surface in haruspex has no trace of a blue-black color- 

 ation, as described in nigrocceruleum Hayw. 



The species named iridescens by LeConte, seems to be repre- 

 sented correctly by the specimen described above, taken by Har- 

 ford or Koebele in Sta. Cruz Co.; it at least agrees very well with 

 the original diagnosis (Ann. Lye. N. Y., 1852, p. 191), except in 

 the statement quoted in the above description, and this lack of 

 distinctness in the carina may be due to an accidental defect in 

 the unique type. I have identified the more abundant form, with 

 less black and more inflated elytra, as parallelocolle Mots., as it 

 agrees well with the description of that species if we assume the 

 immaturity of Motschulsky's type. 



The species described above under the name repens is a very 

 remarkable and isolated type of the subgenus, only in general fea- 

 tures allied to the trechiforme section, though more evidently to 

 that than any other. It is particularly notable in the larger head, 

 which is very deeply retracted virtually to the eyes and in the 

 excessively fine and almost completely unimpressed elytral striae 

 throughout the width, even the seventh being visible. The descrip- 

 tion of vandykei Blaisd., from Mendocino Co., seems to correspond 

 in some degree with the type of repens, but indicates a larger spe- 

 cies, having the prothorax equally wide at base and apex, and in 

 length equal to the basal width, and not having the base wider than 

 the apex and much exceeding the medial length, as is the case in 

 repens; it differs especially, however, in the sides of the prothorax, 

 which in vandykei are said to be sinuate at base, becoming parallel 

 before the hind angles, which are right; in repens the sides are ob- 

 lique and very nearly straight basally, the hind angles obtuse 

 though very sharp; repens differs also in having the fifth elytral 

 stria briefly and feebly deepened at apex, not "strongly grooved" 

 at tip. The type specimen is surely immature, and the species is 

 probably piceous in color, with very pale legs, in its normal color- 

 ation.
