2. MACROSTOLA LUTEA. 
Cilleus luteus (Moritz). 
Ips striatus (Schónh.). 
Statura M. straminee et ei valde affinis, minor, luteo-testacea ; elytris striato-punctatis, 
interstitiis haud lineatis. Long. 2 lin., lat. } lin. 
Habitat in America centrali, apud Cumanam, &c. 
Of the form and appearance of M. straminea, to which it is very closely allied. Con- 
siderably smaller, luteo-testaceous; the head and thorax very faintly punctate; scu- 
tellum impunctate; elytra longitudinally convex, with the suture depressed, punctate- 
striate, without any line between the striæ. In other respects as in M. straminea. 
Easily distinguished from M. straminea by its smaller size, luteous colouring, more 
sparing and feebler punctuation, by the depressed suture of the elytra, and chiefly by the 
absence of the line between the strize on the elytra. 
From Cumana. 
Genus CONOTELUS.

Caput sulcis antennariis, epistomate porrecto ; oculis basin capitis attingen- 
tibus. Labrum integrum. Palpi labiales incrassati. Elytra levissime 
seriatim punctata vel striata. Abdomen segmentis primo et secundo 
brevissimis, tertio et quarto magnis, quinto elongato-conico, maris seg- 
mentulo anali dorsali auctum ; fimbriis angustis, lateribus parallelis. 
Small, narrow, convex, elongate, tapering from before backwards. Head moderate. 
Epistome slightly porrect. Eyes large and projecting, and occupying the whole side of 
the head from the antennze to the base. Antennal grooves well marked and very con. 
vergent. Antenne (Pl. XXXV. fig. 8a) scarcely so long as the head: the first article 
a little enlarged on the outside; second as large, globular; third longer than any of the 
five following, which become shorter and thicker by degrees; the ninth, tenth, and 
eleventh forming a thick and globular club, truncate at the end. Labrum entire. Man- 
dibles small, sharp at the point, the point with two or three small teeth or serrations 
behind it. Mentum short, broadly and feebly emarginate, with a fissure in the midst. 
Maxillary lobe coriaceous, strongly bearded on the inner side. Maxillary palpi short ; 
first article very small, second short and dilated on the outside, third short and cylin- 
drical, last article as long as the rest united, cylindrical, and truncate at the apex. Ligula 
(Pl. XXXV. fig. 8e) coriaceous, with a small, rounded, membranaceous lobe at each of 
its anterior angles. Labial palpi robust: first article very small ; second very large, 
thick, rounded, and truncate; third also large, but not quite so large, truncate.  Pro- 
thorax not quite so broad as the elytra, transverse, convex. Elytra leaving the last 
three abdominal segments exposed, either striate or punctate in rows, although in some 
species so faintly as to be almost imperceptible. Abdomen elongate, tapering to the 
extremity: the first two segments very short, the next two long, the last elongate-
