ClCINDELID.E AND CARABIDyE 59 



Lec., which it evidently is not, as oregonensis is said to be blue-black, 

 with the prothorax almost opaque and densely, intricately rugose, 

 the elytra almost twice as wide as the prothorax and, together with 

 the head, proportionally smaller, narrower and much more finely 

 and densely rugose than in teedatus; its length is 21.3 mm. 



Of the common serratus Say there seems to be a rather well marked 

 subspecies as follows: 



Carabus serratus ssp. vegasensis nov. Similar to serratus in coloration, 

 general form and sculpture throughout, but with the elytra not feebly 

 convex and very gradually declivous laterally, but strongly convex with 

 the sides rapidly and more steeply declivous; elytral sculpture a little 

 stronger, the punctures of the close-set interstitial series separated by 

 more deeply impressed transverse lines. Length 17.0-17.5 mm.; width 

 7.2-7.4 mm. New Mexico (Las Vegas and also from an unrecorded 

 locality); also one, unlabeled, from the Levette collection, possibly from 

 southern Colorado. 



Of serratus I have a good series marked Pennsylvania and Wash- 

 ington State; vegasensis seems to be a more southern modification. 



In the Crotch table of Carabus, tatumi Mots., is given as a syn- 

 onym of mceander Fisch.; this is far from being the fact, as the fol- 

 lowing description of tatumi, given by Motschulsky, w r ill show: 



. " Carabus tatumi Mots. Color et statura C. serrati Say, sed elytris 

 imbricato-striatis, cancellis distinctis, elevatis; oblongus, subconvexus, 

 supra nigro-subcyaneus, limbo paulo dilutiore; capite fere glabro; 

 thorace capite duplo latiore, quadrate, antice arcuatim angustato, postice 

 punctato, latioribus marginatis, reflexis; angulis posticis rectis, apice 

 rotundatis, modice prominulis; elytris thorace paulo latioribus, subovatis, 

 antice truncatis, i6-striatis, interstitiis subconvexis, transverso-rugatis, 

 4, 8 et 12 catenato-interruptis, laevis, 9 long. 8 1. lat. elyt. 3 1. lat. 

 thor. 2^/3 1. De la Hudson-Bay, dans 1'Amerique arctique." 



It seems to be related closely to serratus Say, but of more slender 

 form and stronger sculpture; it is recorded as a distinct species in 

 the Munich catalogue but by Horn (Trans. Am. Ent. Soc., 1870, p. 

 70) is said to be serratus; however, as this author, just above, 

 makes Calosoma prominens Lec., the same as peregrinator Guer., 

 complete dependence cannot be placed on the reference. Hud- 

 sonicus Mots., is probably mceander. Gladiator Mots., is said by 

 Horn (1. c.) to be baccivorus Fisch. 



Calosoma Weber. 



In this genus and the closely related Callisthenes, there are still 

 a number of species not represented in my collection, such as pro-
