LACCOPHILUS. 13 
terminal ventral segment of the female bears only an indistinct longitudinal series of 
punctures on each side of the middle. It differs from L. levipennis by the narrower 
form and different colour, by the hind tarsi being broader and shorter, and by the last 
ventral segment in the male being more elongate, and much more acuminate in the 
middle behind. 
15. Laccophilus optatus. 
Breviter ovalis, sat convexus, pernitidus, testaceus, elytris fusco-piceis, testaceo variegatis, fascia subbasali 
flammulata conspicua.

Hab. Nicaraeva, Chontales (Janson). 
This species has the prosternal process elongate, and the male without any trace of 
coxal file, and may therefore be placed at the commencement of group 5. The male 
only is known to me; it has the apical ventral segment without truncation or sinuation, 
and impressed on the left side (in the natural position) of the middle, and the apical 
portion of its surface rather closely covered with elongate punctuation; the front and 
middle tarsi are very slightly incrassate. The yellow fascia near the base of the wing- 
cases extends from the shoulder to very near the suture ; the portion near the suture, 
however, is a little isolated from the rest of the band by a slight interruption of the 
darker colour; there are also a yellow mark on the lateral margin about the middle and 
a very imperfect band of pale marks some distance in front of the apex, the apex itself 
being also pale. The resemblance to its nearest ally, L. /atifrons, is very considerable 
so far as colour is concerned; but the form is much broader, the surface is more shining, 
and the male characters are different. 
16. Laccophilus suavis. 
Laccophilus venustus, var.?, Sharp, Trans. Roy. Dubl. Soc. n. s. 1. p. 296. 
Ovalis, angustulus, sat convexus, nitidus, politus, testaceus, elytris castaneis, fascia lata subbasali, altera 
abbreviata pone medium interdumque macula laterali testaceis; prosterni processu apice elongato ; 
abdomine parum strigoso. . 
Long. 12 lin. 
Hab. Mexico, Cordova (Sallé). 
A rather narrow, somewhat convex, shining insect, with the head and thorax yellow, 
the latter somewhat clouded with brown on the front and hind margins in the middle ; 
the elytra are of a chestnut-brown colour, with a broad transverse fascia near the base 
yellow, and beyond the middle with a much shorter irregular fascia not nearly 
reaching the suture; this latter band or spot appears to be variable; and there is 
sometimes a spot of yellow colour on the side margin about the middle. The under 
surface is clear yellow; the ventral segments only obscurely strigose. The male has 
the tarsi scarcely incrassate, and has a very obscure coxal file consisting only of five or
