the Salpingides and Agnaihides from the Melandryidce to form 
a tribe which they denominate SimpUcitarses (see table p. 357, 
under Pedilidce) . They divide this tribe into the above-men- 
tioned two groups, but only describe the latter, with its sole 
genus Agnathus and the species A^ decoratus (Germar), 1. c. 
p. 181, with its larva and pupa, pp. 184-187. This species in 
all its stages is also figured with details. 
Leconte (New Col. N. Amer. i. pp. 146-147) gives the follow- 
ing table of the classification of his tribe Melandryini : — 
I. Anterior coxae with a distinct exterior fissure. 
A. Anterior coxae separated by prosternum. Groups. 
1. Joint 3 of antennae longer than 4 1. Penthes. 
2. Joint 3 of antennae equal to 4 2. SynchrocB. 
B. Anterior coxae contiguous. 
1. Frontal suture distinct ; trochantin yisihle 3. Melandryce, 
2. Frontal suture and trochantin not visible 4. Serropalyi. 
II. Anterior coxae without exterior fissmej trochantin not visible. 
A. Anterior coxae contiguous 6. DirccecB. 
B. Anterior coxae separated by prosternum 6. Orchesicc. 
Of these groups, 1 and 2 contain only the single genera Pmthe and Synchroa 
(Newm.) ; the third includes Notlius (Oliv.), Phryyanophlus (Sahib.), Emmcsa 
(Newm.), Mclandrya (Fab.), and Prothalpia (Lee.) j of the others Leconte 
gives the following table : — 
Group 4. SEimoPALPi. 
I. Middle coxae contiguous Xylita (Payk.). 
II. Middle coxae separated by mosostornum. 
A. Joint 4 of max. palpi wider than 2 and 3. 
1. Pubescence prostrate. 
* Antennae thick, outer joints transverse; last joint of max. palpi 
securiform Carehara (Lee.). 
t Antennae slender ; last joint of max. palpi long, cultriform. 
Spilotus (Lee.). 
2. Pubescence erect; antennae slender; last joint of max. palpi seemi- 
form Z^7ora (Muls.). 
B. Max. palpi serrate, joints 2 and 3 as wide as 4. . 
1. Joint 3 of hind tarsi shorter than 2, emarginate ; last joint of max. 
palpi long, cultriform. 
*■ Thorax elongate, lateral margin effaced in front, obsolete behind. 
Hypulus (Payk.). 
t Thorax quadrate, lateral margin distinct behind, effaced in front. 
Marolia (Muls.). 
2. Joints 2 and 3 of hind tarsi equal, not emarginate ; max. palpi ser- 
riform, last joint elongate, securiform. . . . Serropalpus (Hell.). 
C. Max. palpi not serrate, joints 2 and 4 equal in width, 4 elongate. 
Enchodes, g. n. 
Group 6. DmciE.®. 
I. Max. palpi with last joint cultriform; terminal spm’s of tarsi moderate.
