or less, generally rather vajrnely, maculate or blotched. The hind 

 tibiae are either red or green, usually the former, and have ten to four- 

 teen spines in the outer series. 



The sui)raanal ]>hite is pretty regularly triiio^'ilar, the ai)ex never 

 obtusangulate and generally has a median transverse ridge of greater 

 or less distinctness. The furcuhi is generally a mere triangular tooth 

 shorter than the last dorsal segment, but in one 8i)ecies is wanting and 

 in others forms a pair of slender spines a little longer than the last 

 dorsal segment. The eerei are of modj^ate wulth and invariably forked 

 more or less distinctly, sometimes the upi)er, sometimes the lower fork 

 the longer, or they have a strongly ungulate median process beneath, 

 which stands for an inferior branch. The subgenital plate is variable, 

 but is generally rather broad (but sosnetimes very narrow) anil gener- 

 ally a little, in one sjjecies greatly, elevated apically. 



The species, nine in number, are of small or medium size, occasion- 

 ally a little above the medium. Some species or other of the group has 

 been reported from every part of the I'nited States excepting Alaska 

 and California, and is known also fnmi the immediately neighljoring 

 parts of the Dominion of Canada west of the (ireat Lakes, but none 

 have been reported from Ontario or Quebec, where they doubtless 

 exist, nor from the Lower Mississippi Valley, where they also i)robably 

 occur; nor is a single species known from any jiart of Mexico.

(Plate XXII, fig. 7.) 



MelanopUis aJpiniis HHrNEiiI, MS. 



Of rather small size, brownish fuscous, more or less ferruginous 

 above, luteotestaceous below, with a distinct i)ice(ms postocular band. 

 Head feebly prominent, luteotestaceous, sometimes with an olivaceous 

 tinge more or less deeply infuscated above, sometimes confined to two 

 obli<[ue stripes on either side, the outer following the margin of the 

 eye and contluent with the postocular piceous band; vertex gently 

 tumid, elevated a little above the level of the pronotum, the interspace 

 between the eyes nearly twice (male) or fully thrice (female) as broad 

 as the tirst antennal Joint; fastigium rather strongly declivent, shal- 

 lowly (male) or scarcely and broadly (female) sulcate; frontal costa 

 nearly or quite percurrent, sube(iual, scarcely narrower than the inter- 

 space between the eyes, sulcate at and sometimes below the ocellus, 

 biseriately punctate above: eyes moderate, not prominent, about as 

 long as the intraocular portion of the genae; antennae luteons or rufous, 

 more or less feebly infuscated apically, about two thirds (nmle) or half 

 (female) as long as the hind femora. Pronotum rather shcut, feebly 

 expanding posteriorly, the disk more or less ferruginous, the lateral 

 lobes luteous on the i)rozona, except the broad, piceous, almost unbroken 

 baud across the upper half j disk broadly convex, passing into the ver-
