A NEW CARABUS AND CYCHRUS, WITH MISCELLANEOUS 



NOTES ON COLEOPTERA. 



BY THOS. L. CASEY, ST. LOUIS, MO. 



Among a large series of Coieoptera collected by Mr. C. H. T. Town- 

 send in the northwestern part of Mexico and forwarded to me some years 

 ago, I note an interesting new Carabus, which may be described as 

 follows : — 



Carabiis Towtiseiidi, n. sp. — Somewhat similar to Forreri, Bates — 

 Ann. & Mag., N. Hist, ser. 5, IX., p. 320 — from Durango, but narrower 

 in form, the elytra having bimilarly close-set unimpressed series of very 

 minute punctures, but having each only two series of larger, widely-spaced, 

 impressed fovese, the inner of the three series of Forreri being wholly 

 absolete, the middle series only present in basal half and the outer extend- 

 ing only to apical fourth, the lateral margin more narrowly reflexed and 

 with bluish reflection. Length, 21 mm.; width, 9 mm. 



The single specimen in my cabinet was taken at Meadow Valley, 

 six miles south of Colonia Garcia, Chihuahua, Mexico, in the Sierra 

 Madre Mountains, at an elevation of 7,300 feet. 



Cychrus pusiulosus, n. sp. — Black, dull in lustre, with shining elytral 

 tubercles ; head coarsely punctato-rugose, with well-marked supra-orbital 

 ridges, the front but feebly elevated at the middle ; prothorax rather 

 wider than long, the sides broadly rounded anteriorly, becoming oblique 

 and nearly straight toward. the base as in Hemphiiii, ihe angles obtuse, the 

 surface coarsely punctato-rugose and dull, the margins very finely reflexed; 

 elytra oval, having each three series of large, widely-spaced, rounded and 

 polished tubercles, increasing in size to the summit of the declivity and 

 even more conspicuous than in tuber ailat us, though less numerous, the 

 intervening surfaces with single series of small tubercles, the interspaces 

 also minutely and irregularly tuberculose or granulose, dull and lustreless. 

 Length, 17 mm.; width, 8 mm. Washington State. 



The single female before me differs from ttiberculatus, not only in its 

 oblique sides of the prothorax toward base, but in its smaller size, less 

 robust form and stronger elytral tubercles. The prothorax of Hemphilli, 

 Rickseckeri 2ir\d pustulosus is oblique 'and nearly straight at the sides 

 toward base, while in tuberculatus the sides are broadly sinuate pos-- 

 teriorly, the basal angles being right. 



The European Cryptophilus integer, Heer., seems to be cosmopolitan 

 in distribution, and, although unknown to me at the time of revising our' 



May, 1905.
