HELOCHARES. 75 
2. Helochares sallzi. 
Elongato-ovalis, subdepressus, nitidus, piceus, limbo dilutiore; antennarum basi, palpis tarsisque testaceis ; 
crebre, fere fortiter punctatus; palpis elongatis, oculis magnis. 
Long. 33, lat. 2 lin. 
Hab. Murxico, Cordova (Sal/é). 
Head distinctly punctate; clypeus with an irregular transverse series of larger 
punctures on either side near the front; clypeal suture marked by larger punctures, 
and with a few irregularly placed larger punctures behind it on either side. Labrum 
very largely exposed. Thorax very distinctly punctate, and with a very distinct trans- 
verse series of punctures on either side near the front, and with a much shorter and 
more irregular series on each side behind the middle. Elytra distinctly punctate, the 
punctures towards the extremity obsolete, with a distinct series of punctures along the 
middle, and two other less distinct series external to this. Mentum finely grooved on 
either side, but along the middle with a large smooth space, becoming broader in front ; 
submental area very definitely limited, somewhat finely grooved. Prosternum not at 
all carinate ; mesosternum obscurely prominent in the middle near the coxe. 
Although I have seen but a single individual of this species, I think it distinct from 
some other very similar undescribed South-American insects by the greater development 
of the punctuation of the upper surface. 
3. Helochares championi. (Tab. II. fig. 14.) 
Breviter ovalis, parum convexus, nitidus, livide testaceus; antennarum basi, palpis. tarsisque testaceis; capite 
thoraceque crebre subtiliter, elytris adhuc subtilius punctatis; palpis mediocriter elongatis; oculis 
minoribus. 
Long. 23, lat. 1? lin. 
Hab. Guatemata, Guatemala city 5000 feet, Duefias, San Geronimo (Champion) ; 
Nicaragua, Chontales (Belz). 
Head rather small, distinctly punctate. Thorax finely but distinctly punctate; elytra 
still more finely but nevertheless distinctly punctate, the serial punctures very indistinct. 
Mentum very coarsely and deeply rugose punctate; submental area rather short, bearing 
a few coarse punctures. Prosternum slightly compressed along the middle, and forming 
an angle in front. Mesosternum very slightly swollen in front of the coxe. 
This species is readily distinguished from the two just described by the shorter legs 
and palpi, smaller eyes, and numerous other subordinate characters. In the more 
translucent specimens the wing-cases have a peculiar appearance of bearing a pattern 
consisting of fine longitudinal pale lines separated by broader streaks of dark colour ; 
and in certain individuals this dark colour is further broken up by numerous trans- 
verse lines of the pale colour. 
A specimen of the latter variety from Chontales is figured.
