2. Tetragonotes militaris. (Tab. xxv. figg. 23, 24, 25.) 



Tetragonotes militaris, Harold, Coleopt. Hefte, xiii. p. 11 (1875) \ 

 Hob. Guatemala 1 ; Panama, Volcan de Chiriqui 3000 feet {Champion). 



Without having seen the type it is impossible to say whether I rightly refer the 

 numerous and variable specimens obtained by Mr. Champion to the above species. 

 Some of these agree very well with Harold's description, except that in none can 

 the elytra be called pubescent as in T. oculata; they are, on the contrary, rather 

 shining, and only in the light- coloured specimens is a very fine pubescence visible at 

 the sides. The following varieties are worth noticing : — 



Var. a. Head and thorax fulvous ; elytra dark bluish black. 



Yar. b. Head, thorax, antennae, and the breast blackish, the rest as in var. a. 



Var. c. Testaceous or fulvous, the posterior part of the elytra bluish black. 



Var. d. Head and thorax blackish, the lateral margin of the latter testaceous ; elytra with a transverse band 



at the base and another below the middle bluish black. 

 Var. e. Elytra entirely testaceous, the thorax as in var. b. 



Between these varieties intermediate degrees of coloration are not wanting, and if 

 the species is correctly referred to T. militaris, Harold, it is evident that author only 

 knew the form with bluish elytra; the margin of the thorax in the dark-coloured 

 specimens seems to remain of a testaceous colour, as in the type. T. militaris resembles 

 in shape and structure the preceding species ; the head and thorax show a fine but 

 distinct punctuation, and the posterior tibiae are not so curved as in T. oculata, as 

 Harold also remarks. 



Captured in plenty on the Volcan de Chiriqui by Mr. Champion, in company with 

 T. oculata. 



3. Tetragonotes fasciaticollis. 



Black ; upper part of the head, the base of the femora and tibise, flavous ; thorax flavous, remotely punctured, 

 a longitudinal band on the disc black ; elytra black, very finely punctate-striate. 



Length 2| lines. 



Head closely punctured at the vertex, the punctures of elongate shape ; the frontal tubercles strongly raised, 

 bounded behind by a prominent transverse ridge ; the extreme base of the vertex black, the rest of the 

 face testaceous, the labrum piceous ; palpi filiform ; antennse black, the third and fourth joints of equal 

 length, the intermediate joints somewhat dilated (the apical ones wanting) ; thorax scarcely longer than 

 broad, subquadrate, the disc rather flattened, transversely depressed in front of the basal margin, the 

 sides obsoletely angulate before the middle, broadly flavous, the middle of the disc occupied by a longi- 

 tudinal black band which is greatly and rather suddenly narrowed near the anterior margin, the surface 

 very remotely and rather strongly punctured, covered with a few scattered hairs; elytra very finely 

 punctate-striate, black, opaque, sparingly clothed with short, fulvous pubescence, the lateral margin (in 

 one specimen) more distinctly fulvous ; legs flavous, the apices of all the femora and those of the tibia;, 

 black ; tarsi piceous, the breast and abdomen piceous or black, the abdominal segments margined with 

 flavous.
