A long series in the Fry collection connect the numei'ous forms of 

 this very variable insect, which may be known by the deep, transverse, 

 laterally foveate, inter-ocular sulcus, the smooth head and prothorax, the 

 coarsely punctato-striate, bristly elytra, and the powerful curved forceps 

 (sixth ventral segment) of the male. The elytra in the type of 8. fasciata 

 are testaceous, with a large, triangular, post-scutellar patch, the suture 

 thence to beyond the middle, and two transverse fasciae (one submedian 

 and the other just before the apex), black. The sutural marking is some- 

 times wdiolly or in part obsolete and the ante-apical fascia extended to the 

 tip or altogether wanting. One specimen in the Fry collection has 

 the elytra wholly black ; in another they are black, with a broad, com- 

 mon, subapical fascia testaceous ; a third has two fasciae (basal and 

 median, neither reaching the suture), and the apex, black. C. rujiceps 

 has the antennae in part, and the knees, and sometimes the prothorax 

 also, more or less infuscate, and the black subapical fascia oblique 

 (extending, however, to the tip in two of the five examples in 

 Mr. Bryant's collection), a specimen wanting this marking forming the 

 var. subohllteratum of Pic. The 6 penis-sheath, etc., are precisely 

 similar in the forms described by the two authors. C. vitticolle 

 Champ., from Nicaragua, has a somewhat similar S -armature. 



4. — Colpartlirum reedi, n. sp. 



Elongate, narrow, shining ; uigro-piceous or obscure castaneous, the elytra 

 •with a greenish or brassy lustre, the basal halves of the femora, the tibiae to 

 near the apex, and the basal joint of the intermediate and posterior tarsi in 

 part, testaceous ; the head and elytra with a few, very long, erect, setiform 

 hairs. Head smooth, the deep transverse inter-ocular depression bifoveate, the 

 eyes moderately large, separated by about the width of one of them as seen 

 above ; antennae long, joint 11 in <S about as long as 9 and 10 united, in $ a 

 little shorter. Prothorax subcordate, as long as broad, smooth, transversely 

 depressed on each side at about the middle, the basal groove deep. Elytra 

 long, much wider than the prothoi-ax, compressed at the sides below the 

 humeri, acuminate posteriorly ; very coarsely, closely striato-punctate, the 

 punctures deep, becoming much finer beyond the middle and there placed 

 in well-detined striae, the interstices narrow and transversely confluent 

 between the seriate punctures on the anterior half, broader and convex 

 towards the apex, 3, 5, 7, and 9 each with a few scattered, fine, setigerous 

 iujpressions. Femora strongly clavate.
