SCOLOCHRUS. , 127 
coloured; from S. albilabris and its varieties by the close punctuation in connection 
with the different colour ; and from 8. jfotens by the colour of the thorax and the 
elytral pattern. It is, however, not improbable that S. panamensis is a variety of 
S. feetens ; but, taking into consideration the great variability to which these insects 
are subject, additional specimens are required to come to a more definite conclusion. 
Scolochrus fotens (p. 63). 
To the locality Panama, add :—Taboga I. (Champion). 
A male of this species, which sex was unknown to Suffrian, was obtained by 
Mr. Champion ; it agrees in most respects with the female, but the red colour is 
replaced by yellowish-red, the eyes are contiguous, and the thorax is finely and rather 
closely punctured. 
Scolochrus sulcipennis (p. 63). (Tab. IV. fig. 4.) 
To the locality Panama, add:—Volean de Chiriqui, David, Caldera, Taboga I. 
(Champion). 
Many specimens of this species were obtained by Mr. Champion in Chiriqui. It proves 
to be more constant in coloration than is usually the case in this genus; amongst these 
Chiriqui examples, however, are some in which the sutural portion of the elytra is more 
or less yellowish-white. S. sulcipennis has the upper surface entirely opaque. 
The reference to the Plate was accidentally omitted on p. 63. 
16. Scolochrus maculicollis. (Tab. XX XVIII. fig. 9.) 
Piceous, the head and a spot on the anterior part of the thorax black, the latter finely punctured ; elytra strongly 
.subgeminate punctate-striate, the sutural and lateral margins, a narrow transverse band at the base and 
another below the middle, black. 
Var. The thoracic spot obsolete ; elytra fulvous, with the margins and a spot at the shoulders black. 
Length 2 lines. 
Head black, sparingly punctured ; the labrum and oral organs fulvous; eyes (9) not closely approached ; 
antenne black, the lower joints stained with fulvous at their base; thorax narrowly transverse, strongly 
narrowed from the middle to the apex, the surface very finely but not very closely punctured, the punctures 
_ a little coarser at the sides, the latter with an obsolete transverse depression near the base, pale fulvous, 
the disc with a smaller or larger black spot placed at the middle of the anterior margin and a short piceous 
stripe in the centre; scutellum black ; elytra with distinct strie of punctures, the stria placed somewhat 
in pairs, the interstices also impressed with scattered punctures (those near the suture very closely 
approached in pairs), the surface fulvous, a narrow transverse band at the base and another below the 
middle, widened at the sides and connected along the lateral and sutural margins with each other, black ; 
the pygidium and the sides of the abdomen nearly white; legs fulvous, the femora more or less darkened 
or stained with piceous, the posterior tibiew often paler. 
Hab. Panama, Bugaba, David in Chiriqui (Champion). 
S. maculicollis is very similar in coloration to S. fetens, Suffr.; but differs from it in 
the punctuation of the elytra. In S. feetens the thorax is crowded with small punctures
