14 LAEV^ OF THE PRIONIN^. 



but from European descriptions it is more aberrent from Parandra 

 than is Parandra from tbe Prioninse and has been placed by Perris in 

 the Aseminse. 



Osten-Sacken ^ gives a good description of Parandra, regarding it 

 as most nearly allied to the Lepturinas. This is only superficially so, 

 as the fundamental character is the position of the inferior retractor 

 muscles of the head, which are attached in a deep fovea behind the 

 gula, as in Prioninse; also, the sides of the epicranium behind the 

 front are fused and are not entirely angulate as in Lepturinse. 



Le Conte places Parandra and Spondylis in a separate family, 



but says, '4t is more natural to regard them as subfamilies, having 



the same relation to each other as the subfamilies and tribes of 



Cerambycidse. 



Mallodon dasystomus Say. 



Form robust, cylindric; texture smooth, shining, sparsely hairy, 

 the hairs castaneous; eighth and ninth sternites very shiny, inter- 

 segmental skin between ampuUae smooth. 



Epistoma with two broadly triangular lobes projecting over the 

 extremities of the clypeus; front produced in a distinct dull carina 

 which is more prominent at sides, less corneous than that of other 

 prionines. Mandibles short, pointed, outer face rugose, indistinctly 

 carinated on inner upper face. Labrum suborbicular, sparsely 

 covered with hairs, broadly rounded and densely ciliate in front. 

 Three indistinct ocelli. Joints of palpi short; last maxiUary equaling 

 last labial, cylindric, about one-half length of last joint of antennae, 

 roundly truncate at tip. Ligula broad and fleshy. Subfossal process 

 reduced to a broadly obtuse tubercle. 



Anterior portion of lateral zone, of pro thorax bearing group of 

 about six fleshy, conical, chitinous- tipped spines, as also a short 

 fleshy lobe, roughly papillate, which may often be nearly obsolete. 

 Eusternal area of prothorax not entirely distinct. 



Last abdominal segment large; anal lobes protruding dorsally, 

 sparsely pubescent. Spiracles narrowly oval. Pleural discs distinct 

 on first and second abdominal segments, faint on next three, rugose. 



Pupa: Form as in adult; head glabrous; disc of pronotum beset 

 with fine erect asperities, and a few on mesonotum and metanotum; 

 abdominal tergites regularly and more thickly beset with coarser 

 asperities, which extend on to lateral zone; anterior margin of third, 

 fourth, fifth, and sixth segments bearing a curved carinate projection 

 under which fits a fleshy projection from posterior margin of anterior 

 segment. 



Described from specimens labeled Hopk. U. S. No. 12294a, from 

 which a large series of adults was reared. Collected by Mr. J. B.
