long in proportion to the others, but the surface rough aud cor- 

 rugated, not with a hard smooth dorsal plate, as in many Tineidae, 

 Tortricidae, Cossidae, etc., since it is not a boring insect. The eight 

 pairs of abdominal proplike tubercles , which we should hardly regard 

 as homologous of the abdominal legs, are, like those of the Panorpidae, 

 simple tubercles armed with a spine. The 1 0th or last abdominal seg- 

 ment is armed with a pair of dorsal spines, each arising from a tubercle. 

 The singular flattened and fluted setae represented by Chapman are 

 unique in Lepidopterous larvae. He also describes a trefoil-shaped 

 sucker on the under side of the 9th and 10th abdominal segments, 

 »very unusual«: though as it appears to be paired it does not, as 

 Chapman thinks, seem to me to indicate »a further point of relation- 

 ship to Limacodids«. 



Chapman states that »the head is retractile, so far, that it may 

 occupy the interior of the 2d thoracic segment«, and he says that «the 

 antennae are remarkably long for a lepidopterous larva«. He remarks 

 that there are two strong mandibles, with four brown teeth«, and 

 adds: »Two pairs of palpi are also visible — two and three-jointed, 

 apparently those usual in lepidopterous larvae, but I have not defined 

 their relations. There is also a central point (spinneret?). 



The labrum is less divided than usual in lepidopterous larvae, but 

 it is not except in this respect much unlike that of Tineids e.g. Graci- 

 laria (See Dimmock's Fig. 2. p. 100. Psyche, HI). The four-jointed 

 antennae, ending in two unequal setae, are of very unusual size and 

 length, and so are the maxillary palpi, which are much larger than in 

 any caterpillar known to me, and are greatly in disproportion to the 

 maxillary lobes. The maxilla itself differs notably from that of other 

 caterpillars; what appears to be the lacinia is palpiform and 2-jointed. 

 The labium and its palpi are much as in Gracilaria, but the palpi 

 appear to be 3-jointed, with a terminal bristle (it is possible that there 

 are but two joints). Unlike the larva of 3Iicroptcrijx that of Erioce- 

 phala does not appear to possess a well marked spinneret; while it is 

 easy to see it in the former genus, in Eriocephala I can only detect a 

 lobe, which appears to be simply the rudiment (anläge) of a spin- 

 neret (unless the latter is in my specimens bent under the head) ; but 

 the organ needs further examination on fresh specimens. It would be 

 interesting if it should be found that the spinneret is in a generalized 

 condition, _^as compared with that of Micropteryx. 



The pupa. Unfortunately we are as yet ignorant of the pupa 

 form. Dr. Chapman has only found the head-piece of the pupa, but 

 refers it to the »Incompletae«, and thinks it probable that the pupa 

 has the »3d and following abdominal segments free«.
