688 BYRRHIDZ. 
Hab. Panama, Volean de Chiriqui below 4000 feet (Champion). 
This species to a considerable extent connects the C. hyphydroide-forms with the 
C. succinctum-forms. The white pubescence is not sufficiently diffuse to give a grey 
appearance to the wing-cases, but forms small spots, giving rise to a pretty flecked 
appearance. ‘The surface is polished as in C. hyphydroide, and the under surface is 
punctate in a manner intermediate between that of C. hyphydroide and that of 
C. succinctum. ‘The antenne are about 1$ millim. long. There is much punctuation 
along the front margin of the thorax, and a deep depression there, not extending to 
the base; this depression is in some specimens separated into two by an obscure 
elevation of the middle; there is but little setosity on the elevated disc. The setosity 
of the elytra is rather scanty, but definite, and does not very much conceal the shining 
surface. The punctuation of the under surface is not dense or coarse along the middle, 
and there is not a great deal of punctuation on the metasternum. Four specimens. 
Oue of them is a variety of shorter, more oblong form, with the white spots not united 
into a fascia. 
6. Chelonarium succinctum. 
Chelonarium succinctum, Chevrolat, Le Naturaliste, ii. p. 260 (August 1880) *. 
Hab. Mexico, Teapa (Pilate 1, Sallé); Guaremaua, Panzos (Champion). 
This is an oval species, variegated on the elytra with much white hair, but with 
little tawny setosity. It is readily distinguished from C. scabrosum by the small 
antenne, only about 14 millim. long. C. gravidum has also short antenne, but is a 
rather larger insect, of more oblong form, with very dense punctuation of the under 
surface. 
Of four specimens named C. succinctum in Sallé’s collection, three are perhaps this 
species, the other being C. gravidum. Chevrolat’s description is very poor, and as 
it is contained in a work not easily procurable, we here reproduce it :—‘ Long. 6 mil., 
lat. 3 mil. EHlongato-oblongum, nigro-brunneum, nitidum, dense et minutissime 
striatum et breviter pubescens, fascia postica arcuata alba; prothorace semiarcuato, 
lateribus valde reflexo, intra canaliculato, basi crenato, supra scutellum truncato, nigro- 
brunneo nitido, dense minuteque punctato; scutello subtriangulari plano; elytris 
ovalibus convexis, versus medium latioribus, minute punctulatis, breviter griseo- 
pubescentibus, fascia obliqua alba ante apicem ad marginem ducta; corpore infra 
punctulato, rubido. Teapa, 2 ex. a D. L. Pilate datum.” 
With regard to this and all the following species, I may remark that I have not seen 
a sufficient number of specimens to justify me in forming any positive opinion about 
them.
