4 MEMOIRS ON THE COLEOPTERA 



acute lateral margins fully attaining the base; elytra similarly elongate, 

 convex and widest behind the middle, the slightly converging sides 

 feebly and evenly arcuate thence to the base, without humeri, more 

 rapidly rounding and converging behind; punctures small, feeble and 

 sparse, a little stronger and less sparse laterally; legs stouter, third joint 

 of the hind tarsi barely three times as long as wide. Length (cf ) 19.5 

 mm.; width 6.6 mm. California (Tulare Co.) without more definite 

 record. 



Differs from parvicollis in its larger size, more obovoidal hind 

 body, stouter mandibles, larger prothorax, with the converging sides 

 in basal half straight, and in the stouter legs and tarsi, the legs 

 being similarly notably long however. The large female noted 

 under my description of parvicollis is the female of procerus Csy. 



Dromochorus Guer. 



It is difficult to understand how the species that I described under 

 the name sericeus could have been united with belfragei. Its much 

 shorter and broader form and deep clear-cut punctures of the elytra, 

 impart so radically different a habitus that only surmise and con- 

 jecture on the part of those not knowing the species could have led 

 to that conclusion. As to pruininus, the very conservative might 

 consider it a subspecies of belfragei, but the much larger size, very 

 much stouter form and evident purple bloom, wanting in belfragei, 

 would, at any rate, make it a very distinct subspecies by no means 

 a synonym . 



Cicindela Linn. 



The species described by Mr. Leng under the names robusta and 

 bowditchi are wholly unknown to me and are decidedly doubtful 

 as to position in the series; they evidently do not belong together, 

 but I can state nothing further at present. The other species can 

 be assigned to the following 35 groups, which coincide generally 

 with those denned by Mr. Leng though with some departures in 

 sequence or organization, as will be noted. No attempt has been 

 made to indicate the taxonomic rank of the names given under the 

 various groups; they are however all species or subspecies and 

 synonyms are not included ; those to be described further on in the 

 present paper are indicated by an asterisk. 



i Celeripes group. 

 Comprises so far as known only celeripes and cursitans of LeConte.
